    Volume of a cuboid is \[12\text{ }c{{m}^{3}}.\] Find the volume (in\[c{{m}^{3}}\]) of the cuboid if its sides are double.

    A)  24                              

    B)    48      

    C)    72                              

    D)    96                              

    Correct Answer: D

    Solution :

    Volume of a cuboid \[=12\,c{{m}^{3}}\] \[\Rightarrow l\times b\times h=12\,c{{m}^{3}}\] When the sides are doubled, the volume of cuboid \[=2l\times 2b\times 2h\] \[96\,c{{m}^{3}}\]
