Step 7 Objective
Know and use the formula for the volume of a cuboid; calculate volumes and surface areas of cuboids and shapes made from cuboids.

What if pupils find this a barrier?
Ensure that pupils know the correct formulae for areas, perimeters and volumes and how to work them out.
Encourage pupils to use interlocking cubes to make shapes with various volumes. Ensure that pupils realise that three-dimensional objects have surface area as well as volume.
Give pupils opportunities to explore problems of fixed volume, e.g. 'A cuboid is made from 72 cubes. What is the largest surface area?'
