"It was covered with pitch, 300 cubits long, 50 cubits wide, and 30 cubits high. However, the actual size of the ark cannot be determined because the biblical account does not specify the type of cubit. If the Egyptian cubit was used, the Ark's dimensions could range from 129 metres long, 21.5 metres wide and 12.9 metres high to 165 metres long by 27 metres wide and 16.5 metres high. If the Sumerian cubit was used, the metric equivalents would approximate 155.2 metres in length, 25.9 metres in width and 15.5 metres in height. This proportion of length to width (6 to 1) is used by modern naval architects and is a very stable shape, unlike the cube-shaped ark of the Epic of Gilgamesh. Traditional pictures of the ark typically show an unresearched depiction (something shaped like a boat). The Hebrew text uses the word tebah or "box" to describe the Ark."
