Students complete nine fill-in-the-blank problems about the volume formula, unit cube definition, and cubic unit vocabulary. The matching activity pairs four sets of dimensions — including 3 × 4 × 5 cm and 6 × 2 × 7 cm — with their computed volumes.
Matching prism dimensions to their volumes requires students to apply V = l × w × h independently for four different rectangular prisms, consolidating the formula across varied dimension sets.

Volume of Rectangular Prisms
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The formula for the volume of a rectangular prism is V = l × w × h.
2. A small cube with side length 1 unit used to measure volume is called a unit cube.
3. Volume is measured in cubic units such as cm³ or in³.
4. A rectangular prism has three dimensions: length, width, and height.
5. A rectangular prism is a 3D shape with six rectangular faces.
6. A prism 10 cm × 5 cm × 2 cm has a volume of 100 cm³.
7. The volume of a cube with side length 4 m is 64 m³.
8. If each layer has 8 unit cubes and there are 6 layers, the volume is 48 cubic units.
9. Doubling the height of a rectangular prism doubles its volume.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
3 cm × 4 cm × 5 cm
→ 60 cm³
100 cm³
6 cm × 2 cm × 7 cm
→ 84 cm³
84 cm³
8 cm × 3 cm × 3 cm
→ 72 cm³
60 cm³
5 cm × 5 cm × 4 cm
→ 100 cm³
72 cm³
