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.
