    The volume of a cube is 125 cm3. The surface area of cube is:

    A)  \[120%\]                    

    B)  \[8m\times 6m\]

    C)  \[\frac{5}{2}(9+5\sqrt{3})sq.cm\]               

    D)  \[\frac{5}{2}(13+5\sqrt{3})sq.cm\]

    Correct Answer: C

    Solution :

    Let the dimension of the cube be 'a' cm. \[\frac{125\pi }{6}c{{m}^{2}}\] \[8\pi cm\] \[\frac{1}{2}\] \[\frac{2}{3}\] \[\frac{1}{4}\] The surface area \[\frac{3}{4}\]
