- Surface area of cube is 24 in²
In this question we have given volume of cube that is 8 in³. But we know that volume of cube is a³. So ,
So , cube root of 8 is ,
- Therefore, value of a is 2 inches .
Now , we are finding surface area of cube . We know that surface area of cube is 6a² . So ,
- 6 ( 2 )²
- 6 ( 4 )
