Question

The rainfall on a certain day was 6 cm how many litre water fell on 3 hectare filled on that day

Answer 1

According to the question,
Height of rain water=6cm=0.06m
Area over which the rain fell=3hectres=3×10000sq.metres=30,000sq metres.

So, volume of water=0.06×30,000=1800 cubic metres.
Now, 1 cubic metre=1 kL

Hence, amount of water=1800 kL=18,00,000 L

Hope this helps!
