Frustums WORKSHEET
Frustums WORKSHEET DESCRIPTION
This worksheet is perfect for challenging the brightest learners.
In section A, they will need to find the volume of circular and square-based frustums. This may involve thinking about similar shapes. Section B then requires the surface areas of three frustums.
Section C will again require some thinking about similar triangles to help find both the volume and surface area of a circular frustum and a square-based frustum. An extension question involves finding the angle of the sectors used to form a frustum.
All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions
Students should be confident with area of circles and sectors, Pythagoras' Theorem, and similar shapes before tackling this worksheet. These prerequisite skills are essential because frustum problems often involve working with circular cross-sections, finding missing lengths using right-angled triangles, and using the properties of similar triangles to determine unknown dimensions.
