Question

the edge of a cube x is​

Answer 1

so..... ab kya Kare............

volume- x^3

Answer 2

Volume of a cube is given by edge*edge*edge or edge3edge3

If each edge is tripled, that is previously it was s, and now it is 3s.

Then the volume will be 27 times as that of previous volume.

Previous edge length = s units, previous volume = V = s3s3. 
New edge length = 3s units, new volume

V'= (3s)3=33∗s3=27s3(3s)3=33∗s3=27s3=27∗=27∗V
