What was the Ark’s length in the dimensions given by Genesis?

Genesis gives Noah’s Ark a length of 300 cubits.

Genesis 6:15 specifies the Ark’s dimensions as 300 cubits long, 50 cubits wide, and 30 cubits high. The length-to-width-to-height proportions are therefore 6:1:0.6, a shape that is long and relatively low rather than ship-like in the modern sense.

A cubit was an ancient unit based broadly on the length of a forearm, but its exact value varied across cultures and periods. Consequently, translations may convert 300 cubits into different modern measurements. The biblical number itself is firm even though its meter or foot equivalent is not.

The text presents the Ark as a large survival vessel with rooms, three levels, a door, and a window. It does not describe a rudder, sails, or a conventional method of navigation. Modern engineering studies sometimes examine whether the proportions would provide stability, but such studies do not establish the narrative’s historical status.
