Volume Rectangular Prisms Worksheet

Volume is the amount of space a solid figure takes up, and rectangular prisms are where fifth graders first learn to measure it. Once students understand that a prism can be filled with unit cubes, the formula V = l × w × h stops being something to memorize and starts being something that makes sense. This volume rectangular prisms worksheet gives students focused practice multiplying three edge lengths, working backward from a known volume to a missing edge, and applying both skills to problems they might really meet at home or at school.

The sheet opens with a formula box so the relationship stays visible while students work. Part A shows three labeled rectangular prisms and asks students to multiply length, width, and height, then label the answer in cubic centimeters, cubic inches, or cubic feet. Part B reverses the thinking: the volume is given along with two edges, and students divide their way back to the missing dimension. Part C finishes with two word problems about packing unit cubes into a gift box and stacking storage bins. Use this 5th grade geometry worksheet as guided practice after a lesson, as morning work, as a quick review before a unit test, or as a homework page. The included answer key makes checking fast for teachers and for students working independently.

What’s Included

• 1 print-ready PDF worksheet
• Answer key
• 8 volume problems: 3 labeled prisms, 3 missing-edge problems, and 2 real-world word problems

This resource helps kids learn volume in three ways. First, the labeled diagrams connect the symbols in the formula to the actual edges of a solid, so students can see which number belongs where. Second, the missing-edge problems build flexible thinking, because a student who can work backward from a product truly understands the relationship rather than just following steps. Third, the word problems in this volume rectangular prisms worksheet move the skill into real containers — gift boxes and storage bins — which is exactly how volume questions appear on standardized tests and in everyday life.

Teachers and parents can extend the lesson in simple, hands-on ways. Give students a handful of centimeter cubes and a small box and ask them to predict the volume before filling it, then compare the count to the formula. Ask students to measure a cereal box, a shoebox, or a desk drawer at home and calculate its volume. Challenge them to build two different prisms that have the same volume but different dimensions, which quietly introduces factor pairs. Finally, play the Volume Song while students work so the vocabulary sticks.
