Question

If each side of a cube is doubled, how many times will its volume increase?

Answer 1

when side be x =》
vol. of cube = side ^3 = x^3

when side ,be 2x
vol. pf cube = 8x^3


vol. of cube increases 8 times

Answer 2

Answer:

The volume will get 8 times.

Step-by-step explanation:

  Let the side of the given cube be 'a'

Volume of this cube = $a^3$

  Given,

Side of the Cube is doubled, therefore,

'a' becomes '2a'

Thus, the new volume of the cube =$(2a)^3$

=$8a^3$

Thus we can say that the volume will increase to 8 times the initial volume or the volume will increase by 7 times.
