Lesson details
Key learning points
- A composite solid can be decomposed to make the volume easier to calculate.
- Completing the solid may be a more useful method.
- Decomposing and rearranging parts of the solid may be beneficial.
Keywords
Volume - The volume is the amount of space occupied by a closed 3D shape.
Compound shape - A compound shape is a shape created using two or more basic shapes. A composite shape is an alternative for compound shape.
Common misconception
Pupils may only using given measures in their calculations, even when these are not the lengths required for substitution into a volume formula.
Encourage pupils to annotate diagrams to show how the are breaking down a compound/composite shape. Pupils should label the diagram with any new lengths needed. They may need to use Pythagoras or trigonometry to find these new lengths.
