For example, if the wall length is 30 feet, the width is 2 feet and the height is 3 feet, the volume of gravel needed to construct this wall is 30 x 2 x 3 = 180 divided by 3 = 60 cubic feet.
The total amount of gravel needed for this wall is 80 cubic feet of gravel. Divide the total cubic foot volume of gravel by 15 to determine the number of tons of gravel to purchase.
