Question

Find the total surface area of the cube given below.

Answer 1

B. 96 cm²

1) For cubes, the total surface is given by 6 times the area of the square that has in this case, a side length of 4 cm.

2) So we can write:

$\begin{gathered} A=6a^2 \\ A=6(4)^2 \\ A=6(16) \\ A=96cm^2 \end{gathered}$

3) Therefore the answer is B. 96 cm²
