  • Question
  • In a shower, 5 cm of rain falls. The volume of water that falls on 1.5 hectares of ground is:


  • Options
  • A. 75 cu. m
  • B. 750 cu. m
  • C. 7500 cu. m
  • D. 75000 cu. m

  • Correct Answer
  • 750 cu. m 

    Explanation
    1 hectare = 10,000 m 2

    So, Area = (1.5 x 10000) m2 = 15000 m2.

    Depth = 5 m = 1 m.
    100 20

    ∴ Volume = (Area x Depth) = 15000 x 1 ❩m3 = 750 m3.
    20
