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 $m^2$
So, Area = (1.5 x 10000) m2 = 15000 m2.
Depth =$ \dfrac{5}{100}m = \dfrac{1}{20}m$
ą®Volume = (Area x Depth) = $(15000 \times \dfrac{1}{20})m^3 = 750 m^3$
1 hectare = 10,000 $m^2$
So, Area = (1.5 x 10000) m2 = 15000 m2.
Depth =$ \dfrac{5}{100}m = \dfrac{1}{20}m$
ą®Volume = (Area x Depth) = $(15000 \times \dfrac{1}{20})m^3 = 750 m^3$
