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.
It is 65.0 cu ft, approx.
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
13.5 square feet.
17.11 square feet.
40inch = 3.33 foot 48 inch = 4 foot so 4 x 4 x 3.33 = 53.328 or 53 and a third cubic feet - as you have three measurements it needs to be in cubic feet either that or the pallet square footage is based only on 40 x 48 3.33 x 4 = 13.32 square feet

The pallet's area is about 12.07 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.
