    If six cubes of 10 cm edge are joined end to end, then the surface area (in sq. cm) of the resulting solid is

    A)  3600

    B)  3000

    C)  2600  

    D)  2400

    Correct Answer: C

    Solution :

     By joining six cubes end to end, we get a cuboid\[60\text{ }cm\times 10\text{ }cm\times 10\text{ }cm\]. \[\therefore \]  Surface area \[=2(60\times 10+10x+10\times 60)\]\[=2600\text{ }c{{m}^{2}}\]
