According to Genesis 6:15, what was the stated length of Noah's Ark?

According to Genesis 6:15, the stated length of Noah’s Ark was 300 cubits.

The same verse gives the ark’s proportions as 300 cubits long, 50 cubits wide, and 30 cubits high. A cubit was an ancient unit commonly connected with the length of a forearm, but its exact value varied by culture and period. Depending on the cubit used, 300 cubits is often estimated at roughly 135 to 157 metres, though converting the biblical measurement into a single modern figure is uncertain.

The proportions produce a long, relatively narrow rectangular vessel. Modern naval architects have sometimes discussed the ratio as a stable barge-like form, but such studies do not prove the historical construction of the ark. The Genesis passage is a textual specification, not a surviving engineering drawing. The length should also be kept separate from the width and height: 50 cubits is the width, while 30 cubits is the height.
