large it was that size would limit the number on it.

The cubit is an ancient unit of length based on the length of the forearm from the elbow to the tip of the middle finger. Cubits of various lengths were employed in many parts of the world in antiquity, during the Middle Ages and as recently as Early Modern Times.
The earliest attested standard measure is from the Ancient Egypt and was called the royal cubit.
In Ancient Egypt, cubit rods were used for the measurement of length. A number of these have survived: two are known from the tomb of Maya, the treasurer of Tutankhamun, in Saqqara; another was found in the tomb of Kha (TT8) in Thebes. Fourteen such rods, including one double cubit rod, were described and compared by Lepsius in 1865. These cubits range from 523 to 529 mm (20.6 to 20.8 in) in length, and are divided into seven palms; each palm is divided into four fingers and the fingers are further subdivided.

The Holy Bible records Noah's ark as being 300 cubits long, 50 cubits wide, and 30 cubits high.
This would make the ark 515 to 520 feet long, about 86 feet wide, and 51.5 to 52 feet high with 3 decks or floors.
