Use this worksheet to reinforce how to find the volume of a rectangular prism by counting the number of unit cubes.
Practice Finding the Volume with Unit Cubes
Have you just begun to teach the concept of volume to your students? If so, you are probably using a lot of manipulatives and hands-on activities to teach this concept. Whether it be constructing figures with connecting cubes, or showing how you can pack an object with a non-standard measurement item, a concrete understanding of volume is important before jumping straight into working with a formula.
With this math worksheet, students will practice looking at a variety of rectangular prisms and cubes. They must determine how many cubes make up the length, width, and height. Once students have found each dimension, students can calculate the volume of each shape. This can be done by using the formula, V = L × W × H.

Tips for Differentiation + Scaffolding
In addition to independent student work time, use this worksheet as an activity for:
- Guided math groups
- Lesson warm-up
- Lesson wrap-up
- Fast finishers
- Homework assignment
- Whole-class review (via smartboard)
For students who may need a bit of a challenge, encourage them to practice finding the volume of figures with only the dimensions listed.
If there are students who need additional support, consider providing students with a set of connecting cubes to construct each figure. After determining the dimensions, students can break apart each figure to determine how many cubes were used to make each object.
