1
Determine the length, width and depth measurement of the space, if necessary, using the tape measure or ruler. Measure the dimensions in either feet or yards but whatever unit of measurement you use, use it for each dimension. Write these measurements down on the paper.

2
Multiply the length measurement by the width measurement. Multiply your answer by the depth measurement. If you measured in yards, your answer is in cubic yards already. If you measured in feet, proceed to the next step.

3
Divide cubic feet by 27 to find the measurement in cubic yards. For example, if the length is 40 feet, the width is 20 feet and the depth is 2 feet, the volume will be 1,600 cubic feet (40 * 20 * 2). Divide 1,600 by 27 to get 59.25 cubic yards.
