Best Answer

The amount of gravel needed to cover 252 square feet depends on how thick (that is, deep) you want the gravel.

If you want the gravel to be 3 inches thick...

Convert the measurement to the same units. We'll use feet.

3 inches = 1/4 foot

Multiply the thickness times the area to get volume in cubic measure.

1/4 feet x 252 feet = 63 cubic feet

Gravel in the US is usually sold by the cubic yard, which is 27 cubic feet

Thus, 63/27 = 2 1/3 cubic yards

2 1/3 cubic yards of gravel will cover 252 square feet of area to a dept of 3 inches.
