Question

Matt and Mindy each built a rectangular prism that has a lenth of 5 units, a width of 2 units, and a height of 4 units. Matt use cubes that are 1 cm on each side. Mindy used cubes that are 1 inch on each side. What is the volume of each prism?

Answer 1

The volume of a prism is just its width times its height times its length.


`V = whl`


`V = 2 * 4 * 5`


`V = 40`

So we know the volume is 40 units. But which units?

Matt used centimeters as his units, so his rect. prism's volume would be 40 cm³. Mindy's would be 40 in³.
