GCSE Maths Practice: surface-area

Question 6 of 10

This question introduces cuboid surface area calculations with different side lengths.

‹ ›

\( \begin{array}{l}\text{Find the surface area of a cuboid with dimensions } 5\,\text{cm}, 3\,\text{cm}, 2\,\text{cm}.\end{array} \)

Choose one option:

Calculate each face area, sum, multiply by 2. Check units (cm²).

A cuboid has 6 rectangular faces. Calculate area of each pair of identical faces: length × width, length × height, width × height. Then sum all pairs and multiply by 2: SA = 2(lw + lh + wh). For dimensions 5 cm, 3 cm, 2 cm: SA = 2(15 + 10 + 6) = 62 cm². Practicing different dimensions reinforces understanding and improves speed in exams.
