Year 9 Volume Worksheets | Printable PDFs
Year 9 Volume worksheets for Year 9 Maths (Key Stage 3). Students aged 13–14 may already know how to calculate the volume of prisms, including cuboids, using standard volume formulas. For extra practice with this see Year 8 Volume Worksheets. In year 9 more advanced students extend their knowledge to finding the volume of pyramids, cones and spheres, as well as compound 3D shapes.
There are a number of formulas for the volume of 3D shapes that are usually provided to students in an exam. It's still a good idea however, to memorise the formulas. Volume of a cone, V = ⅓πr²h. Volume of a sphere, V = ⁴⁄₃πr³. Volume of a pyramid, V = ⅓Ah (where A is the area of the base of the shape). In year 11 students learn how to solve questions involving frustums.

Common Questions about Year 8 Volume
How do you find the volume of a compound 3D shape?
Split the shape into simpler 3D shapes, find the volume of each part, then add the volumes together. If part of the shape is missing, find the full volume first and subtract the missing part.How do you find the volume of a cuboid made with cubes?
Count the cubes along the length, width and height, then multiply them together. The volume of a cuboid is length × width × height.What is the formula for the volume of a prism?
The volume of a prism is area of cross-section × length. First find the area of the front face, then multiply by how far the prism extends.
Year 8 Volume Common Mistakes
Common Mistake 1
Forgetting to split a compound 3D shape into simpler parts before calculating volume.Common Mistake 2
Counting only the visible cubes instead of using length × width × height.Common Mistake 3
Using the perimeter of the cross-section instead of the area when finding the volume of a prism.
