Question

The area of a face of a cube is 225 sq.cm. Find its volume.​

Answer 1

Step-by-step explanation:

Area of a face of a cube = a²

(where a is the side of cube)

So, a² = 225

a = 15

Now , volume of cube is a³

So , volume = a³ = 15 × 15 × 15

= 3375 cm³

Answer 2

Examplular Answer:-

Let a be the side of the cube. Given that T.S.A = 384 sq. cm.

i.e., 6a 2

=384

⇒a 2

= 6

384=64

∴a= 64

=8cm

Hence, Volume =a cube

=8 cube

=512cm cube

Hence proved//
