Students learn how to find the surface area of cubes and cuboids using nets and 3D drawings. As learning progresses students are challenged to find an unknown length of a cuboid when the surface area is given.

The start of the lesson challenges students to imagine the hidden faces of a cube while following a pattern. At the end they investigate different surface areas when given a fixed volume.

##### Differentiated Learning Objectives

- All students should be able to measure the surface area of a cuboid by counting.
- Most students should be able to calculate the surface area of a cuboid.
- Some students should be able to find an unknown dimension of a cuboid when given its surface area.
