For Edexcel GCSE Mathematics, you need to calculate volumes and surface areas of prisms, cylinders, cones, spheres, pyramids and composite solids. Higher tier students must also handle frustums. This lesson covers all the required formulae and indicates which ones appear on the Edexcel formula sheet.
| Term | Meaning |
|---|---|
| Prism | A 3D shape with a uniform cross-section (same shape all the way through) |
| Cylinder | A prism with a circular cross-section |
| Pyramid | A 3D shape with a polygon base and triangular faces meeting at an apex |
| Cone | A pyramid with a circular base |
| Sphere | A perfectly round 3D shape where every point on the surface is the same distance from the centre |
| Frustum | The solid that remains when the top of a cone or pyramid is cut off by a plane parallel to the base [H] |
The following are given on the Edexcel formula sheet:
