How to solve it: a worked example

Find the volume or surface area. Include units.

1. StartFind the surface area.
2. Six square facesSA $=$ $6$ $s^{2}$ $=$ $6$ $\times$ $6^{2}$ $=$ $6$ $\times$ $36$ $=$ $216$
3. Answer$216$ $\mathrm{cm}^{2}$

Common mistakes to watch for

• Using 3s or s × 3 instead of s³ for a cube's volume.
• Counting only three faces of a prism instead of all six.
• Mixing up square units (surface area) and cubic units (volume).
