Preparing the Ark
14Make for yourself an ark of gopher wood; make rooms in the ark and coat it with pitch inside and out. 15And this is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide, and 30 cubits high. 16You are to make a roof for the ark, finish its walls a cubit from the top, place a door in the side of the ark, and build lower, middle, and upper decks.

Adam Clarke Bible Commentary
Thou shalt make - the length of the ark - three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits - Allowing the cubit, which is the length from the elbow to the tip of the middle finger, to be eighteen inches, the ark must have been four hundred and fifty feet in length, seventy-five in breadth, and forty-five in height. But that the ancient cubit was more than eighteen inches has been demonstrated by Mr. Greaves, who traveled in Greece, Palestine, and Egypt, in order to be able to ascertain the weights, moneys, and measures of antiquity. He measured the pyramids in Egypt, and comparing the accounts which Herodotus, Strabo, and others, give of their size, he found the length of a cubit to be twenty-one inches and eight hundred and eighty-eight decimal parts out of a thousand, or nearly twenty-two inches. Hence the cube of a cubit is evidently ten thousand four hundred and eighty-six inches. And from this it will appear that the three hundred cubits of the ark's length make five hundred and forty-seven feet; the fifty for its breadth, ninety-one feet two inches; and the thirty for its height, fifty-four feet eight inches. When these dimensions are examined, the ark will be found to be a vessel whose capacity was more than sufficient to contain all persons and animals said to have been in it, with sufficient food for each for more than twelve months. This vessel Dr. Arbuthnot computes to have been eighty-one thousand and sixty-two tons in burden. As many have supposed the capacity of the ark to have been much too small for the things which were contained in it, it will be necessary to examine this subject thoroughly, that every difficulty may be removed. The things contained in the ark, besides the eight persons of Noah's family, were one pair of all unclean animals, and seven pairs of all clean animals with provisions for all sufficient for twelve months. At the first view the number of animals may appear so immense that no space but the forest could be thought sufficient to contain them. If, however, we come to a calculation, the number of the different genera or kinds of animals will be found much less than is generally imagined. It is a question whether in this account any but the different genera of animals necessary to be brought into the ark should be included Naturalists have divided the whole system of zoology into Classes and Orders, containing genera and species. There are six classes thus denominated: 1. Mammalia; 2. Aves; 3. Amphibia; 4. Pisces; 5. Insectae; 6. Vermes. With the three last of these, viz., fishes, insects, and worms, the question can have little to do. The first Class, Mammalia, or animals with teats, contains seven orders, and only forty-three genera if we except the seventh order, cete, i.e. all the whale kind, which certainly need not come into this account. The different species in this class amount, the cete excluded, to five hundred and forty-three. The second Class, Aves, birds, contains six orders, and only seventy-four genera, if we exclude the third order, anseres, or web-footed fowls, all of which could very well live in the water. The different species in this class, the anseres excepted, amount to two thousand three hundred and seventy-two. The third Class, Amphibia, contains only two orders, reptiles and serpents; these comprehend ten genera, and three hundred and sixty-six species, but of the reptiles many could live in the water, such as the tortoise, frog, etc. Of the former there are thirty-three species, of the latter seventeen, which excluded reduce the number to three hundred and sixteen. The whole of these would occupy but little room in the ark, for a small portion of earth, etc., in the hold would be sufficient for their accommodation. Bishop Wilkins, who has written largely and with his usual accuracy on this subject, supposes that quadrupeds do not amount to one hundred different kinds, nor birds which could not live in the water to two hundred. Of quadrupeds he shows that only seventy-two species needed a place in the ark, and the birds he divides into nine classes, including in the whole one hundred and ninety-five kinds, from which all the web-footed should be deducted, as these could live in the water. He computes all the carnivorous animals equivalent, as to the bulk of their bodies and food, to twenty-seven wolves; and all the rest to one hundred and eighty oxen. For the former he allows one thousand eight hundred and twenty-five sheep for their annual consumption; and for the latter, one hundred and nine thousand five hundred cubits of hay: these animals and their food will be easily contained In the two first stories, and much room to spare; as to the third story, no person can doubt its being sufficient for the fowls, with Noah and his family. One sheep each day he judges will be sufficient for six wolves; and a square cubit of hay, which contains forty-one pounds, as ordinarily pressed in our ricks, will he amply sufficient for one ox in the day. When the quantum of room which these animals and their provender required for one year, is compared with the capacity of the ark, we shall be led to conclude, with the learned bishop, "that of the two it is more difficult to assign a number and bulk of necessary things to answer to the capacity of the ark, than to find sufficient room for the several species of animals and their food already known to have been there." This he attributes to the imperfection of our lists of animals, especially those of the unknown parts of the earth; and adds, "that the most expert mathematicians at this day," and he was one of the first in Europe, "could not assign the proportion of a vessel better accommodated to the purpose than is here done;" and concludes thus: "The capacity of the ark, which has been made an objection against Scripture, ought to be esteemed a confirmation of its Divine authority; since, in those ruder ages men, being less versed in arts and philosophy, were more obnoxious to vulgar prejudices than now, so that had it been a human invention it would have been contrived, according to those wild apprehensions which arise from a confused and general view of things, as much too big as it has been represented too little."

Jamieson-Fausset-Brown Bible Commentary
And this is the fashion--According to the description, the ark was not a ship, but an immense house in form and structure like the houses in the East, designed not to sail, but only to float. Assuming the cubit to be 21.888 inches, the ark would be five hundred forty-seven feet long, ninety-one feet two inches wide, and forty-seven feet two inches high.
John Gill Bible Commentary
And, behold, I, even I, do bring a flood of waters upon the earth,.... That there was such a flood of waters brought upon the earth, is confirmed by the testimonies of Heathen writers of all nations; only instead of Noah they put some person of great antiquity in their nation, as the Chaldeans, Sisithrus or Xisuthrus; the Grecians and Romans, Prometheus or Deucalion, or Ogyges. Josephus (z) says, all the writers of the Barbarian or Heathen history make mention of the flood and of the ark; and he produces the authorities of Berosus the Chaldean, and Hieronymus the Egyptian, who wrote the Phoenician antiquities, and Mnaseas, and many others, and Nicolaus of Damascus: and there are others that Eusebius (a) makes mention of, as Melo, who wrote against the Jews, yet speaks of the deluge, at which a man with his sons escaped; and Abydenus the Assyrian, whose account agrees with this of Moses that follows in many things; as do also what Lucian (b) and Ovid (c) have wrote concerning it, excepting in the name of the person in whose time it was: and not only the Egyptians had knowledge of the universal deluge, as appears from the testimony of Plato, who says (d), that an Egyptian priest related to Solon, out of their sacred books, the history of it; and from various circumstances in the story of Osiris and Typhon, which name they give to the sea, and in the Chaldee language signifies a deluge; and here the Targum of Onkelos renders the word by "Tuphana"; and the Arabs to this day call the flood "Al-tufan"; but the Chinese also frequently speak of the deluge (e); and even it is said the Americans of Mexico and Peru had a tradition of it (f); and the Bramines also (g), who say that 21,000 years ago the sea overwhelmed and drowned the whole earth, excepting one great hill, far to the northward, called "Biudd"; and that there fled thither one woman and seven men (whose names they give, see Gen 7:13) those understanding out of their books that such a flood would come, and was then actually coming, prepared against the same, and repaired thither; to which place also went two of all sorts of creatures (see Gen 6:19) herbs, trees, and grass, and of everything that had life, to the number in all of 1,800,000 living souls: this flood, they say, lasted one hundred and twenty years (see Gen 6:3) five months and five days; after which time all these creatures that were thus preserved descended down again, and replenished the earth; but as for the seven men and woman, only one of them came down with her, and dwelt at the foot of the mountain.And this flood was not topical or national only, but general and universal: it was brought "upon the earth", upon the whole earth, as the following account shows; and by the Lord himself, it was not through second causes, or the common course of things: and to show it possible and certain, this form of expression is used, "behold, I, even I, do bring"; it was wonderful, beyond the power of nature, and therefore a "behold" is prefixed; it was possible, because the Almighty God declares he would bring it; and it was certain, which the redoubling of the word points at; and would be quickly, since he said, "I am bringing", or "do bring"; just about to do it; wherefore the ark was not so long preparing as some have thought, and the command to build it was not long before the flood came. The word for the flood comes from one which signifies to fall (h), either because of the fall of the waters at it, or because it made all things to fall, wither, and decay, as herbs, plants, men, beasts, and all creatures; or from one that signifies to consume, or to mix and confound, and bring all things to confusion, as Jarchi suggests (i): and the end and intention of it, as here expressed, was to destroy all flesh, wherein is the breath of life, from under heaven; every living creature, men and women, the beasts and cattle of the earth, and every creeping thing on it, and the fowls of the heaven, man principally, and these for his sake. And everything that is in the earth shall die; but not what was in the waters, the fishes of the sea, which could live in the flood. (z) Antiqu. l. 1. c. 3. sect. 6. (a) Praepar.
