GCSE Maths Practice: volume

Question 4 of 10

This question asks for the volume of a triangular prism. Triangular prisms have a triangular base extended along a length.

\( \begin{array}{l}\text{Find the volume of a triangular prism with base 4 cm, height 3 cm, length 10 cm.}\end{array} \)

Choose one option:

Compute base area first, then multiply by length. Remember units.

To find volume, first calculate area of the triangular base: A = 1/2 × base × height. Here base = 4 cm, height = 3 cm: A = 1/2 × 4 × 3 = 6 cm^2. Then multiply by prism length: V = area × length = 6 × 10 = 60 cm^3. Triangular prisms appear in roofs, wedges, and tunnels. Understanding volume calculation helps visualise space inside 3D shapes. Practice with different bases, heights, and lengths to gain confidence. Always write units cm^3.
