Volume and surface area questions range from simple prisms at foundation to cones, spheres and frustums at higher tier. Students must choose the correct formula, substitute values carefully, and give answers to appropriate accuracy.
Our tutors see these errors again and again. Knowing them in advance gives you a head start.
Confusing radius and diameter when substituting into formulas
Forgetting the factor of one-third in cone and pyramid volume formulas
Not including all faces when calculating total surface area
This topic is tested by the following exam boards. Our tutors are specialists in each one.
Area and perimeter calculations cover rectangles, triangles, parallelograms, trapezia and circles. Compound shapes combine these, and higher-tier questions involve sectors and segments of circles.
Geometry & MeasuresPythagoras' theorem relates the three sides of a right-angled triangle and is one of the most practical geometry topics at GCSE. It is used in 2D and 3D problems, coordinate geometry, and combined with trigonometry at higher tier.
Ratio, Proportion & Rates of ChangeDensity problems link ratio work with geometry through the relationship density = mass / volume. Students must rearrange this formula, convert units, and often combine it with volume calculations for 3D shapes.
