Question

In a shower, $5cm$ of rain falls. Find the volume of water that falls on $2$ hectares of ground.

Answer 1

$1$ hectare $=10000m$

then, $2$ hectares $=20000m$

$\Rightarrow$ $2$ hectares $=20000\times 100\times 100=200000000{cm}^2$

RAin falls $=5cm$

Volume of rainfall $=200000000\times 5{cm}^3$

$=100000000{cm}^3$

$=1000m^3$
