Multiply by 1728.
multiply by 12x12x12
There are 144 square inches in a square foot and 1.728 cubic inches in a cubic foot. So you have 7,776 square inches and that would give you 7,776 cubic inches. That would be 4.5 cubic feet.
If you mean 50 inches by 40 inches by 77 inches, the volume would be 98.03 cubic feet. If you mean 50 feet by 40 feet by 77 feet, the volume would be 169400 cubic feet.

Well, first you would have to have the measurement in cubic inches. Divide the cubic inches by 1728 and the result is cubic feet. I would recommend looking up how to do conversions if you want to know how to do it yourself.
First, figure out how many cubic inches are in a cubic foot. A cubic foot is 12 inches x 12 inches x 12 inches, so 12x12x12= the number of cubic inches in one cubic foot. You then multiply the number of cubic inches on one cubic foot by the total number of cubic feet (which in this case is 8) and that will give you the total number of cubic inches in 8 cubic feet. That's a method you can use, now it's up to you to do the math!
2.5 cubic feet = 4,320 cubic inches
