The volume of any object can be measured by how much space it takes up. Volume is most often measured by using some kind of container and taking stock of how much it can hold. The volume of a prism is measured as a three dimensional object, with mass, as explained in the following steps. The formula for such an equation is: volume (v) = length (L) x width (W) x height (H).

Measure the length of your prism with a ruler or tape measure.

Next measure the width of the object.

Finally, measure the height.

Multiply your length, times your width. Now multiply that result times the height. Your formula should look like this: v = L x W x H.

Tip

One example is 10 cm (length) x 3 cm (width) x 5 cm (height) = 150 cm cubed.

Warning

Don't rush through the formula. Take your time to get the right answer.
