  • question_answer In a shower, 10 cm of rain falls. What will be the volume of water that falls on 1 hectare area of ground?

    A)  \[500\text{ }{{m}^{3}}\]                    

    B)  \[650\text{ }{{m}^{3}}\]       

    C)  \[1000\text{ }{{m}^{3}}\]

    D)  \[750\text{ }{{m}^{3}}\]

    Correct Answer: C

    Solution :

    (c): 1 hectare \[=10000\,\,{{m}^{2}}\] Depth/Height of water above ground \[=10\,\,cm=\frac{1}{10}m\] Since, Volume = Depth \[\times \] Area; \[\therefore \]      Volume \[=10000\times \frac{1}{10}=1000\,{{m}^{3}}\]
