In the biblical account of Noah’s Ark, what were the ark’s stated dimensions in cubits?

In the biblical account of Noah’s Ark, its stated dimensions are 300 by 50 by 30 cubits.

Genesis 6 gives the ark’s length as 300 cubits, its width as 50 cubits, and its height as 30 cubits. The passage presents these measurements as instructions given to Noah before the Flood. It also says the ark had rooms, a door in its side, and three levels.

A cubit was an ancient unit generally related to the length of a forearm, but its exact value varied by culture and period. Estimates commonly place the biblical cubit somewhere around 44 to 52 centimeters, so modern conversions are approximate rather than exact.

Using a 45-centimeter cubit would make the ark about 135 meters long, 22.5 meters wide, and 13.5 meters high. The dimensions have prompted comparisons with ship proportions, although the biblical narrative is a religious text rather than a surviving engineering specification.
