Measure the length of the storage space in linear feet.

Measure the width of the storage space in linear feet.

Measure the height of the storage space in linear feet.

Multiply the three measurements together. For example, if the length of the area is 10 feet, the width of the area is 5 feet and the height of the area is 8 feet, multiply 10 x 5 x 8 to give you 400. This resulting number is the amount of storage space expressed in cubic feet.
