Guide to Volume of a prism: Explanation, Diagrams & Worked Examples

Download Printable One Page Guide (PDF)

Explanation:

A prism is a 3D shape that has the exact same 2D shape (the cross-section) running all the way through its length. For any prism: Volume of Prism = Area of Cross-Section × Length.

Always calculate the area of the front cross-section first (whether it is a triangle, a trapezium, or a compound L-shape), and then multiply that area by the depth/length of the prism.

Example 1: A triangular prism has base 8 cm, perpendicular height 6 cm, and length 12 cm. Find its volume.

8 cm 6 12 cm
Area = 12×8×6 = 24 cm²
V = 24 × 12
= 288 cm³

Example 2: A prism has a trapezium cross-section with parallel sides 5 m and 9 m, height 3 m, and length 10 m. Find its volume.

9 m 5 m 3 m 10 m
Area = 5+92×3 = 21 m²
V = 21 × 10
= 210 m³

GCSE Past Paper Volume of a prism Questions & Answers

Past Paper Example 1 AQA Nov 2023 2F Q26 / 2H Q7 3 marks
Here is a prism drawn on an isometric grid.
6 cm
Work out the volume of the prism.
Worked Solution & Mark Scheme (3 marks)
(The volume of a prism is area of cross-section × length)
Area of L-shaped cross-section = (2 × 3) + (1 × 1) = 7 cm² M2
Volume = 7 × 6 = 42 cm³. A1
Answer: Answer 42 cm³
Past Paper Example 2 IGCSE Jan 2020 2HR Q13 3 marks
The diagram shows a prism ABCDEFGH in which ABCD is a trapezium with BC parallel to AD and CDEF is a rectangle.
h cm7 cm12 cm10 cmABCDEFGHDiagram NOTaccurately drawn
BC = 7 cm   AD = 12 cm   DE = 10 cm
The height of trapezium ABCD is h cm
The volume of the prism is 608 cm3
Work out the value of h.
Worked Solution & Mark Scheme (3 marks)
(The volume of a prism is area of cross-section × length)
0.5 × (7 + 12) × h × 10 = 608 M1
⇒ 95h = 608 M1
⇒ h = 608 ÷ 95 = 6.4 A1
Answer: h = 6.4
Past Paper Example 3 GCSE Nov 2020 3H Q9 5 marks
The diagram shows a prism.
40°12 cm10 cm25 cm
The cross section of the prism has exactly one line of symmetry.
Work out the volume of the prism.
Give your answer correct to 3 significant figures.
Worked Solution & Mark Scheme (5 marks)
(The volume of a prism is area of cross-section × length)
Roof triangle height h = 5 × tan 40° = 4.1955 cm M2
Area of cross section = (10 × 12) + (0.5 × 10 × 4.1955) = 120 + 20.977 = 140.977 cm² M2
Volume = 140.977 × 25 = 3524.4 cm³ = 3520 cm³ (3 s.f.) A1
Answer: 3520 cm³
