Question

if the edge of the cube is doubled then its volume?

Answer 1

Answer:

New side = 2a cm. So, new volume =(2a)3cm3=(8a3)cm3. So, the volume becomes 8 times.

Answer 2

Answer:

8a³

Step-by-step explanation:

As we know that volume of a cube is (side)³ here let side be a.

Now in this condition the side is doubled i.e. 2a

So, Now volume will be : (2a)³

=> 8a³
