Will three yards of sand cover 54 sq feet 16 inches deep?

Answer 1

If the question refers to 3 cubic yards of sand then all measurements need to be converted to a common unit for the calculation to be made. Let the chosen unit be feet.

1 cubic yard = 3 x 3 x 3 = 27 cu ft : 3 cubic yards = 3 x 27 = 81 cu ft.

12 inches = 1 foot : 16 inches = 16/12 = 1.333 feet.

Volume of sand required = Area x depth = 54 x 1.333 = 72 cu ft.

The amount of sand will easily fill the space - leaving 9 cu ft = 1/3 cu yard as surplus.
