Question

if each edge of a cube is doubled,how many time will it's volume increase​

Answer 1

Answer:

If edge of a cube is doubled.

Firstly let us look at the side of the cube.

side^3 = volume.

That means side x side x side = volume.

If we double the sides, we get

2 side x 2 side x 2 side = 8 volume.

Hence the volume will increase by its cubic power or it will increase to 8, if we assume that each edge of a cube is defined to be of one unit length.

Answer 2

Answer:

8 times

Step-by-step explanation:

please mark me as brainliest

$let, edge of cube =x\\ volume of cube = x^{3}\\ now, the edge of cube =2x\\ therefore, volume of cube = (2x)^{3}=8x^{3}\\Therefore , the volume of cube is increased by 8times$
