Multiply the width times the length times the height (W x L x H). You can also use our volume calculator to find cubic yardage of a space. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.

Compute the square footage of your yard by using the appropriate volume formula for the shape of your yard. For rectangular yards, multiply the length times the width. For example, if your yard is 10 feet by 15 feet, you would multiply 10 by 15 to get 150 square feet.

Multiply the length, width and depth of the hole in feet to find the total volume in inches. For the example: 1 foot x 2 feet x 0.5 feet = 1 cubic foot. Divide the area by 27 to find the volume of the dirt in cubic yards (because 1 cubic yard = 27 cubic feet).

Multiply the rectangle's length by its width to determine the area in square feet. For example, multiply 15 feet by 12 feet to yield an area of 180 square feet (15 x 12 = 180). Divide the square footage of the rectangle by 9 to convert to square yards: 180 square feet divided by 9 yields 20 square yards (180 / 9 = 20).
