    The area of the base of a rectangular tank is \[6500\,\,c{{m}^{2}}\] and the volume of water contained in it is \[2.6\,\,{{m}^{3}}.\] The depth of the water in the tank is

    A)  2.5 m  

    B)  3 m

    C)  5.5 m  

    D)  4 m

    Correct Answer: D

    Solution :

    \[l\times b=6500c{{m}^{2}},\,\,\,\,l\times b\times d=2.6{{m}^{2}}\] \[=(2.6\times 100\times 100\times 100)\,\,c{{m}^{3}}\] \[\therefore \]      \[d=\frac{(2.6\times 100\times 100\times 100)}{6500}\,\,cm\] \[=\frac{2.6\times 100\times 100\times 100}{6500\times 100}\,\,m=4\,m\] \[\therefore \]      Depth = 4 m
