Question

If the total surface area of cube is 24 $c{m}^2$ and the area of base is 4 $c{m}^2$, then find the lateral surface area of the cube.

• A. 16 $c{m}^2$
• B. 18 $c{m}^2$
• C. 24 $c{m}^2$
• D. 20 $c{m}^2$

Answer 1

The correct option is A 16 $c{m}^2$

Total surface area of cube
$=\text{lateral surface area}+2\times \text{Area of base}$
$\Rightarrow 24=\text{lateral surface area}+2\times 4$
$\Rightarrow$lateral surface area = 24 - 8
= 16 $c{m}^2$
