Question

The lateral surface area of a cube is 324cm^2.find its volume and the total surface area

Answer 1

Heya ✋

Let see your answer !!!

Given that

Lateral surface area of a cube = 324cm^2

Side = ?

Volume = ?

T.S.A = ?

Solution

Let the side of the cube be (x)cm. Then,

L.S.A. of the cube = 4 × l^2

=> 324 = 4 × x^2

=> 324/4 = x^2

=> 81 = x^2

=> x = √81

=> x = 9

Hence , the side of the cube is 9cm.

Volume of the cube = (Side)^3

= (9)^3

= 729cm^3

T.S.A of the cube = 6 × l^2

= 6 × 9^2

= 6 × 81

= 486cm
