Upon heating the length of each side of ...

Upon heating the length of each side of the cube changes by `2%.` The volume of the cube would change by :

A

`1%`

B

`2%`

C

`2//3%`

D

`6%`

Text Solution

Verified by Experts

The correct Answer is:
D
Volume, `V=l^(3)`
`:.(DeltaV)/(V)xx100=3(Deltal)/(l)xx100=3xx2%=6%`
Hence the correct choice is `(d)`.
