How to approach volume with cubes
Volume counts the number of unit cubes that fill a three-dimensional space. A rectangular prism's volume equals length × width × height.
Layer reasoning makes the formula meaningful: length × width counts cubes in one layer, and multiplying by height counts all equal layers.
Learning objectives
- Count unit cubes
- Find rectangular-prism volume
- Use cubic units
Skills to review first
- Multiplication
- Rows and columns
- Length, width, and height
Worked example
Follow the reasoning step by step
Find the volume of a prism 4 units by 3 units by 2 units.
- One layer contains 4 × 3 = 12 cubes.
- There are 2 equal layers.
- Multiply 12 × 2.
- Use cubic units.
Solution: 24 cubic units.
