8 ft × 8 ft × 6/12 ft = 32.0 cubic feet. Add 10% = 35.2 cubic feet. Divide by 27 = 1.30 cubic yards.

Good to know
A paver bedding layer is a nominal 1 in (ICPI). There is no official depth standard for a home sandbox. We calculate at 6 in, the low end of the 6 to 12 in range supplier guides suggest, and you can change the depth. For a sandbox for children buy sand labelled as play sand (look for a silica-free label) and do not use construction or paver sand. Damp sand is heavier than dry sand.
