Lesson details

Key learning points

  1. The surface area of any solid can be calculated by a known method.
  2. The volume of any solid can be calculated by a known method.
  3. Writing an algebraic statement about surface area/volume can be done from a diagram.

Keywords

  • Volume - The volume is the amount of space occupied by a closed 3D shape.

  • 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.

  • Compound shape - A compound shape is a shape created using two or more basic shapes. A composite shape is an alternative for compound shape.

Common misconception

When questions are in context, the length may be described as the depth or height and this can cause some pupils to struggle if they have learned a formula with a particular word.

Remind pupils that the volume of a 3D shape comes from the area of a cross section multiplied by the height or depth. They may need to evaluate a perpendicular length from other given information, using trigonometry or Pythagoras' theorem.

Encourage pupils to use exact values throughout their calculation, and only round their answers at the end to ensure the greatest accuracy.
