Check understanding
- Decompose an L-shaped solid into two cuboids and calculate total volume
- Solve a real-world problem requiring the volume of a composite figure (e.g. a step-shaped structure)
- Explain why splitting a composite solid into rectangular prisms allows calculation of total volume
“If an L-shaped swimming pool is made of two rectangular sections, can your child find the volume of each section separately and add them to get the total volume of the pool?”
