How big was Noah's ark?

Answer 1

Noah's Ark was 300 cubits the breadth of 50 cubits and the height 30 cubits as said in The Bible in Genesis 6:15.

This is about 450 feet long, 75 feet wide and 45 feet high.

"And God said unto Noah "...Make thee an ark of gopher wood; rooms shalt though make in the ark, and thou shalt pitch it within and without with pitch. And this is the fashion which thou shalt make it of: the length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits. A window shalt thou make in the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it." (Gen. 6:14-16)

Noah's ark was 300 cubits long, 50 cubits wide, and 30 cubits tall.

In modern measurements, that would be 135 meters long, 22.5 meters wide, and 13.5 meters tall.
