Question

The rainfall on a certain day was 6 cm. How many litres of water fell on 3 hectares of field on that day?

Answer 1

Area of the filed = 3 hectares
= $3\times 10000$ square metres
= 30000 square meters
Height of rainfall = 6 cm = $\frac{6}{100}{m}^3$
$\therefore$ Volume of rainwater = $30000\times \frac{6}{100}{m}^3$
=$1800m^3$
$\therefore$ Rainwater in litres = $1800\times 1000$
= 1800000 l $(1m^3=1000l)$
= $18\times {10}^5$ litres
