    If diagonal of a cube is \[\sqrt{12}\] cm, then its volume in cubic cm is

    A) 8                     

    B) 12

    C) 24                                

    D) \[\sqrt[3]{2}\]

    Correct Answer: A

    Solution :

    Let a be the side of cube. \[\therefore \] Diagonal of cube \[=\sqrt{3}a\] \[\Rightarrow \]   \[\sqrt{3}a=\sqrt{12}\] \[\Rightarrow \]   \[a=12\,cm\] \[\therefore \] Volume of cube \[={{2}^{3}}=8\,c{{m}^{2}}\]
