GCSE Maths Practice: surface-area

Question 7 of 10

This question reinforces cube surface area calculation with a larger side.

‹ ›

\( \begin{array}{l}\text{Find the surface area of a cube with side length } 4\,\text{cm}.\end{array} \)

Choose one option:

Compute one face first, multiply by 6. Ensure units are squared.

For a cube with side 4 cm, area of one face = 4 × 4 = 16 cm². Multiply by 6 faces to get 96 cm². Understanding this formula helps in calculating materials needed to cover all faces of cubic objects, such as boxes or tiles. Practice with multiple side lengths to reinforce mastery.
