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.

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.
It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
33.5 cubic feet.
259.2593 sq. yards.
