    A tank with a square base has a volume of \[384\text{ }c{{m}^{3}}.\] If its height is \[6\text{ }cm,\] find the length of the side of the square base.

    A)  \[\text{10 }cm\]                             

    B)  \[\text{8 }cm\]

    C)         \[\text{12 }cm\]             

    D)         \[\text{6 }cm\]

    Correct Answer: B

    Solution :

    Volume = Area of square base x Height So, \[384=\text{ }Area\text{ }\times h\] \[\Rightarrow \]  Area of the base \[=\frac{384}{6}=64\,c{{m}^{2}}\] \[\Rightarrow \]Length of the side of the square base\[=8\text{ }cm\].
