In Genesis’s measurements of Noah’s Ark, how long was the vessel?

In Genesis’s measurements of Noah’s Ark, the vessel was 300 cubits long.

Genesis 6:15 gives the ark’s dimensions as 300 cubits in length, 50 cubits in width, and 30 cubits in height. These proportions produce a long, rectangular vessel rather than the ship-like shape often shown in paintings and films.

A cubit was an ancient unit based broadly on the length of a forearm, so its exact modern conversion is uncertain. Depending on the cubit used, 300 cubits is commonly estimated at roughly 135 to 157 metres, or about 440 to 515 feet.

The text gives dimensions but no complete construction blueprint. Modern replicas, including the Ark Encounter structure in Kentucky, use particular interpretations of the biblical measurements and materials.
