    The figure shows a cuboid with a volume of\[180\text{ }c{{m}^{3}}\]. What is the value of 'p' ?

    A)  \[72\]                                                  

    B)                         \[36\]                  

    C)                         \[18\]                                                  

    D)                         \[2\]

    Correct Answer: D

    Solution :

    Volume of the cuboid \[=180\text{ }c{{m}^{3}}\] From the figure, volume is \[(p+3)\,\,(9)\,\,(4)\] \[\Rightarrow \]               \[36(p+3)=180\] \[\Rightarrow \]               \[p+3=5\] \[\Rightarrow \]               \[p=2\]
