In Genesis, what was the total height of Noah’s Ark?

Genesis gives Noah’s Ark a total height of 30 cubits.

Genesis 6:15 records the Ark’s three principal dimensions: 300 cubits in length, 50 cubits in width, and 30 cubits in height. The height is therefore the smallest of the three stated measurements, producing a broad, relatively low vessel rather than a tall structure.

The same chapter says the Ark had lower, second, and third decks. The biblical text does not state the height of each deck, nor does it explain how the space was divided among rooms, animals, food, and Noah’s family.

Exact modern conversions are uncertain because ancient cubits varied. If a cubit is estimated at about 45 centimeters, 30 cubits would be approximately 13.5 meters. That is an estimate, while 30 cubits is the precise biblical measurement.
