Question

What's the lateral surface area of the cube if the length of its side is 6 cm?

• A. $144c{m}^2$
• B. $72c{m}^2$
• C. $36c{m}^2$
• D. $24c{m}^2$

Answer 1

The correct option is A $144c{m}^2$

Given, length of side is 6 cm.

We know that,
Lateral surface area of cube
$=4\times sid{e}^2$
$=4\times 6^2$
$=4\times 36$
$=144c{m}^2$
