Eight feet by eight feet (8' X 8') is a square area. The answer is 64 square feet.But eight times eight feet is 64 (linear) feet, because 8x8=64.
sqrt(8) = sqrt(4) * sqrt(2) = 2 * sqrt(2) = 2 * 1,4142 2,8284(..) To calculate the square root of 2 I needed a calculator. This number is irrational (you can prove that) which means there is no repeating part in the decimals of the square root of 2, and not in the square root of 8 either.
8 feet square is the same as 8 square feet. NOT!8 foot square is 8' x 8' or 64 square feet.
The floor and ceiling are each 72 square feet.In order to calculate the walls, we'd also need to know the height of the room.
