Lesson details
Key learning points
- The surface area of a solid is the sum of the area of all the faces.
- The net of a cuboid can help find the surface area.
- The surface area of a cuboid can be found without drawing the net.
Keywords
Surface area - The surface area is the total area of all the surfaces of a closed 3D shape. The surfaces include all faces and any curved surfaces.
Net - The net of a 3D object is a 2D representation of its surfaces that can be folded up into the 3D object.
Common misconception
When working out the surface area, the pupil may only find the sum of the areas of three faces of a cuboid (for example the visible sides in a 3D drawing), instead of all six faces.
Encourage pupils to sketch the net of the cuboid as part of their solution. This will provide a visual reminder to the pupil to find the area of all six faces, as well as making it easier to check their answer.
