Example 1
Which combination is a sensible simple model of a can with a pointed cone-shaped lid?
Show worked answer
Answer: A cylinder and a cone
- A can has a curved cylindrical body. A pointed circular lid can be approximated by a cone.

Example 3
A simple block model of a bench uses 3 cubes in each of 2 separate stacks. No cubes are shared between stacks. How many cubes are used?
Show worked answer
Answer: 6
- There are 2 stacks, each with 3 cubes.
- 2×3=6 cubes. A block model can approximate a real object.
