How To Calculate Volume

You can calculate volume with an easy to use formula. The standard shapes such as a square or rectangle all use the same formula.

Step 1

Measure the length of the object. For example, a box may measure 10 inches long.

Step 2

Measure the width of the object. The same box may be 10 inches wide.

Step 3

Measure the depth, or height, of the object. In this example the depth will be 10 inches.

Step 4

Insert the measurements into the formula.

Step 5

Multiply the length (L) times the width (W) times the height (H). The formula looks like this: LxWxH For this example, to calculate the volume of the object the formula would be 10 x 10 x 10 = 1,000 cubic inches.
