Step-by-step explanation:

Answer 2

Given that

Lateral surface area of cube is 216 cm sq.

To find

Area of cube

Solution

Let a is the side of cube then

$lateral \: area \: = 4 \times {a}^{2} \\ 216 = 4 \times {a}^{2} \\ a = 7.34cm$

$area \: of \: cube = 6 \times {a}^{2} \\ = 6 \times (7.34 {)}^{2} \\ = 323.25 {cm}^{2}$

hence area of cube is 323.25 sq cm.
