Five centimetres of rain fall during a shower. The amount of water that falls on 1.5 hectares of land is calculated as follows:
A. 75 cu. m B. 750 cu. m C. 7500 cu. m D. 75000 cu. m
Explanation: 10,000 m2 Equals 1 hectare,As a result, the area equals (1.5 x 10000) m2 = 15000 m2.5/100 m = 1/20 m depth.15000 x 1/20 m3 = 750 m3 Volume = (Area x Depth).
