GCSE Maths Practice: volume

Question 9 of 10

This question asks which shapes have volume, identifying 3D solids.

‹ ›

\( \begin{array}{l}\text{Which of these shapes have volume?}\end{array} \)

Select all correct options:

Only 3D shapes have volume. Check if the object has depth.

Volume exists only for 3D objects. A cube and a cylinder have three dimensions: length, width, and height (or radius and height). 2D shapes like squares or circles have area but no volume. Understanding which shapes occupy space is crucial for practical tasks like packaging or construction. For example, a cube with side 3 cm has volume 27 cm^3; a cylinder with radius 2 cm and height 5 cm has V = π×2^2×5 = 62.8 cm^3. Recognising 3D solids also helps visualise cross-sections, edges, and faces.
