Genesis 6:15

The dimensions of the ark, as here given, are somewhat smaller than in the Assyrian account. Assuming that a cubit measured 1½ feet, the ark was 450 ft. long, 75 ft. broad, and 45 ft. high. It will be noticed that the breadth is exactly one-sixth, and the height exactly one-tenth, of the length. In the Assyrian account we miss these proportions. The length is not given, but the height and breadth are the same, viz. 120 cubits, or 180 ft., broad and high. Berossus, the Greek writer of Babylonian traditions, records that the ship of the Flood was 5 stadia (about ⅔ of a mile) long, and 2 stadia (about ¼ mile) broad.
