Question 4 of 10

Calculate the total surface area of a cube with side length 5 cm.

‹ ›

\( \begin{array}{l}\text{Find the total surface area of a cube with side length } 5\,\text{cm}.\end{array} \)

Choose one option:

Multiply the area of one face by 6.

Each face of a cube is a square with area s². Cube has 6 faces, so total surface area = 6 × s² = 6 × 25 = 150 cm². Understanding surface area is important for covering objects with material, painting, or packaging. Visualize each face and count them. Practice with different side lengths to strengthen skills in surface area calculations.
