Topic overview

What you need to know

Volume & Surface Area is a key part of GCSE Mathematics. Build fluency with the method, then apply it to unfamiliar and multi-step problems. Volume = length × width × height. Volume = area of cross-section × length. Works for any prism shape. Volume = πr²h, where r is the radius of the base and h is the height.

Exam tip

Write every stage of your method. Method marks can still be earned when the final answer is wrong.

Revision notes

Core ideas

Secure these ideas first. Say each definition in your own words, then connect it to the topic overview.

  • Volume of a Cuboid: Volume = length × width × height.
  • Volume of a Prism: Volume = area of cross-section × length. Works for any prism shape.
  • Volume of a Cylinder: Volume = πr²h, where r is the radius of the base and h is the height.
  • Volume of a Cone: Volume = ⅓πr²h. It's one third of the volume of a cylinder with the same base and height.

Revision notes

Apply it in the exam

The exam will rarely ask for an isolated definition. Practise selecting the right idea and using it as part of a complete explanation or method.

  • Volume of a Sphere: Volume = (4/3)πr³.
  • Surface Area of a Cuboid: SA = 2(lw + lh + wh). Add up the area of all six faces.
  • Surface Area of a Cylinder: SA = 2πr² + 2πrh. Two circular ends plus the curved surface.
  • Surface Area of a Sphere: SA = 4πr².
