About this printable
Practice rectangular prism volume with eight focused questions and a separate printable answer key. Each exercise has space for a written method, and the answers also appear as readable text below. Use the practice page first, then compare methods as well as final answers. The paired images stay together in this article so the solution can be found without searching for another post.
How to use it
Multiply length, width and height for a rectangular prism. A prism measuring 4 cm by 3 cm by 2 cm has volume 24 cubic centimeters. Think of the base area as one layer and the height as the number of equal unit layers.
Check and adapt
Use cubic units rather than square units. Each prompt gives three perpendicular edge lengths in centimeters. This worksheet concerns solid volume, not surface area or capacity conversions, and assumes the object is a rectangular prism.
