Question

The volume of a cube of edge ‘x’ cm is ‘y’ cm cube .What will be the increased volume ,if the edge of the cube is doubled.

Answer 1

Answer:

8y

Step-by-step explanation:

1.Edge=x

2.Volume=x³=y (or you can continue with x³)

3.If edge equals to 2x

4.Volume=(2x)³=8x³

5.Equate

6.x³=8x³

7.Matlab answer is 8times

means 8y

Answer 2

Note ^ means raised to the power and here ^3 is equal to cube

Answer:

8y

Step-by-step explanation:

Volume of a cube = Edge Cube i.e.

y = x cube

And then if Edge of the cube is doubled then it equals to

(2x)^3 which then equals to 8x cube

Here 8x cube is the Edge Cube

So then y = 8x cube

And to bring 8x into its true form we know that y = x cube

So y now equals to 8y after the edge of the cube is doubled
