Question

The side of a cube is 4m. If it is doubled, how many times will be the volume of the new cube,as compared with the original cube?

Answer 1

Answer:

Step-by-step explanation:

volume of the cube = a^3

volume of the first cube =v1 = (4)^3=4*4*4=64m^3

volume of the second cube = v2 = (4*2)*3= (8)^3=512m^3

on comparing

64m^3/512m^3=1/8

Answer 2

The volume of new cube is 8 times the volume of original cube

Step-by-step explanation:

Side of cube = 4 m

Volume of cube =$Side^3 = 4^3 = 64 m^3$

Side of cube is doubled

New side = $2\times 4 = 8 m$

Volume of new cube = $Side^3 = 8^3 =512 m^3$

Let the volume of new cube is x times the volume of original cube

$64x=512$

$x=\frac{512}{64}$

x=8

Hence the volume of new cube is 8 times the volume of original cube
