In Genesis, what length does the Noah's Ark account give for the ark?

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

Genesis 6:15 lists three measurements for the vessel: 300 cubits long, 50 cubits wide, and 30 cubits high. A cubit was an ancient unit commonly associated with the distance from an adult’s elbow to the end of the hand, so its exact modern equivalent is uncertain. Estimates often place the ark’s length somewhere around 135 to 150 metres, depending on the cubit used.

The dimensions describe a huge rectangular vessel built to preserve Noah, his family, and representatives of the animals during the flood. They are sometimes compared with the proportions of ancient ships, although the biblical account presents the ark primarily as a survival vessel rather than a conventional sailing ship.

The 300-cubit figure is distinct from the ark’s width and height, which are 50 and 30 cubits respectively.
