What are the traditional dimensions of Noah’s Ark in cubits, according to Genesis?

Genesis gives Noah’s Ark dimensions of 300 by 50 by 30 cubits.

Genesis 6:15 states that the ark was 300 cubits long, 50 cubits wide, and 30 cubits high. A cubit was an ancient unit based broadly on the length of a forearm, so its exact modern equivalent varies. Using common estimates, the ark would have been roughly 135 metres long, 23 metres wide, and 14 metres high, though conversions differ.

The biblical description also includes three decks, rooms, and a window or opening. The measurements describe a large rectangular vessel intended for preservation rather than normal sailing. Modern replicas, including the Ark Encounter structure in Kentucky, use these proportions, but a full-scale historical vessel has not been verified by archaeology.
