GCSE Maths Practice: surface-area

Question 2 of 10

This question explains how to calculate the surface area of a cube using the area of one face.

‹ ›

\( \begin{array}{l}\text{Which statement is true about the surface area of a cube?}\end{array} \)

Choose one option:

\( \text{It is 6 times the area of one face} \) \( \text{It is 4 times the area of one face} \) \( \text{It is 12 times the length} \) \( \text{It is the square of the perimeter} \)

Compute one face, multiply by 6. Verify units are squared.

Each cube has six identical square faces. To calculate surface area, find area of one face (side × side) and multiply by 6. For example, side 4 cm → face area 16 cm² → total surface area 16 × 6 = 96 cm². Understanding this method is fundamental for cubic objects in real life, including boxes, dice, and containers. Practice with different side lengths to reinforce mastery of cube surface area calculation.
