Rainfall in an area is 5 cm. The volume of the water that falls on 2 hectares of land is

(c) 1000 m3

Volume of water that falls on 2 hectares of land $=($ Area of the ground $\times$ Amount of rain in $\mathrm{m})$

$=\left(2 \times 1000 \times \frac{5}{100}\right) \mathrm{m}^{3} \quad\left(\because 5 \mathrm{~cm}=\frac{5}{100} \mathrm{~m}, 2\right.$ heactares $\left.=2 \times 1000 \mathrm{~m}^{2}\right)$

$=1000 \mathrm{~m}^{3}$
