Question

if length of each edge of a cube is tripled what will be the change in its volume

Answer 1

Let,
Initial edge= a cm
So,
Volume= a³ cm³
Now,
After tripling,
Edge= 3a
So,
Volume= (3a)³ cm³
= 27a³ cm³
So,
After tripling the volume of the cube will become 27 times its Initial volume.

Hope this helps you!

Answer 2

Answer:

Step-by-step explanation:

Then,

Normal volume=a³

New volume with

a=3a

Volume=(3a)³

           =27a³

Difference in volumes=27a³-a³

                                     =26a³
