There is no answer to this because you are asking for a cubic measurement but providing only two out of three dimensions. You need three
77.78 ft3
It is 65.0 cu ft, approx.
The pallet's area is about 12.07 square feet.
1 cubic foot = 12 x 12 x 12 = 1728 cubic inches The given cube is 40 x 48 x 52 = 99840 cubic inches = 99840/1728 = 57.777 cubic feet
There is not enough information to figure the cubic feet of the pallet. The depth would be needed for that. There is enough information to figure the surface area, which is measured in square feet, square inches, etc. To find the area of an object, take the length times the width. 40 inches X 48 inches = 192 square inches or 16 square feet.
5.55 square feet.
That is approximately 40 cubic feet. - note,your measurements may not be accurate, I deal with many pallettes and have never seen a 40x40. - 48 " per side is standard.
15 sq. feet
12.25 square feet.
5 square feet
13.5 square feet.
17.11 square feet.
