If 2cm of water fell on a sq cm what weight of water fell on a hectare or 10000 sq m?

Answer 1

If 2cm fell on any space we can assume that 2cm fell everywhere. Rainfall is assumed in problems to be standard across a region.

1 hectare = 10,000 sq metres.

2cm = 0.02 metres.

10,000 square metres x 0.02 metres = 2,000 cubic metres.

2,000 cubic metres = 2,000,000 litres

1 litre is* defined as the volume of 1 kilogram of water under standard conditions.

So, 2,000,000 litres of water would weigh 2,000,000 kilograms.

* Actually the definition has changed by the relationship still exists.
