In a shower, 5 cm of rain falls. The volume of water that falls on 1.5 hectares of ground is:
75 cu. m
750 cu. m
7500 cu. m
75000 cu. m
Explanation:

1 hectare = 10,000 m2

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

Height is taken 5cm, because the flow rate is assumed constant over the entire surface on which the rain falls.
