Question

The total surface area of the given cube shown below is ___$m^2$, while the lateral surface area is ___$m^2$.

• A. 24, 10
• B. 24, 16
• C. 16, 24
• D. 16, 20

Answer 1

The correct option is B 24, 16

The total surface area of a cube = $6a^2$
Lateral surface area of cube = $4a^2$
Where a is the length of each side.
The length of each side of the cube given above = 2 m
On substituting the values in the formulas, we get:
Total surface area = $6\times 2^2=24m^2$
Total surface area = $4\times 2^2=16m^2$
