Answer 2

Answer: if a no. is doubled then it's cube is eight times the cube of the given no.

Step-by-step explanation:suppose we will take the no. 2

If we double it, it becomes 4

Cube of 2 is 8 and cube of 4 is 64

We will divide cubes of both no.s =64/8

= 8

So it becomes eight times.

You can also try this on no.s like 3 and 4 and you will get the same answer
