12 ft x 12 inches/ 1 foot = 144 inches
6 ft x 12 inches/ 1 foot = 72 inches
144in x 72in x 6in = 62208 cubic inches of sand
8*5*1/2 = 20 cubic feet.

It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
In order to answer this question you must first convert the measurements into inches(20 ft= 240 in), so the new problem is 240*240*3, which equals 172800. Then you must convert the inches into yards by dividing 172800 by 36, which equals 4800. So it takes 4800 yards of sand to fill a sandbox 20 feet by 20 feet by 3 inches.
