@cicerone imposter,
You can not figure that out by square feet...or feet ^2...but volume, or cubic feet (feet ^3)
Noah's Ark had about 1.5 million feet ^3 or 1.5 million cubic feet...
Cubit = 18 inches, 300 cubits = 450 feet, 50 cubits = 75 feet, 30 cubits = 45 feet
450 feet x 75 feet x 45 feet = 1,518,750 feet ^3
The average giraffe is 204 feet ^3
204 feet ^3 x 600 = 122,400 feet ^3
1,518,750 feet ^3 - 122,400 feet ^3 = 1,396,350 feet ^3
