If your hole is 36” deep and 10” wide, the calculation is 3.14 x 5 x 5 x 36 ÷ 1728. This gives you 1.6 cubic feet. If you forget the 1728 it is simply 12” x 12” x 12” or the number of cubic inches in a cubic foot.

Keep in mind that mulch is sold by the cubic yard. One cubic yard of the material covers a 324-square-foot area an inch deep. So, to determine your total, multiply your square footage by the depth in inches desired, then divide by 324. Here's your formula: Square footage x desired depth / 324 = cubic yards needed.

Measure the length and height of the block in inches and then substitute the values in the equation square feet of block = (length of block x height of block) / 144. For example, a standard cement block measures 16 x 8 inches, so it covers 0.89 square feet — (16 x 8) / 144 = 0.89.

Divide the desired depth for your landscape rock in inches by 12 to convert it to feet. For instance, if you want the rock to be 2 inches deep, divide 2 by 12, which equals 0.1667 feet. Multiply the length by the width by the desired depth in feet for your landscape rock to find the number of cubic feet you will need.

Calculate the percentage of reinforcement with the formula P = 8.33UA/t, where P is the percentage and t is the thickness. For example, the percentage of reinforcement of a 30-inch slab with two layers of No. 6 rebar spaced 4 inches on center is P = 8.33_6_0. 43/30 = 0.72 percent.
