The volume of a cube in `m^(3)` is numerically equal to its surface area in `m^(2)`. The volume of cube is :

A

`1000m^(3)`

B

`8m^(3)`

C

`256m^(3)`

D

`216m^(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Here `L^(3)=6L^(2)` or `L=6m`
`:.` Volume`=216m^(3)`
or `(d)` is the answer.
