Question

if we Two times the side of a cube then how many will be it's volume ​

Answer 1

Let original side of the cube be x.

New side of the cube = 2 x

Now, original volume = x³

New volume = ( 2 x )³ = 8 x³

Thus, the volume becomes 8 times.

Answer 2

Volume of Cube = a^3

a is doubled so new a formed is 2a

V = (2a)^3

= 8a^3
