Question

The rainfall on a certain day was 12 CM. How many litres of water fell on 3 hectares of land on that day
​

Answer 1

Answer:

Amount of water in litres = (Area of field in sq.metre X Rainfall in m)/1000

                                        =(30000 X 0.12)/1000

                                        =3.6 l

                                       

Answer 2

Answer:

250000 days that is

20833.333333333 years

Step-by-step explanation:

As 1 hectare contains 1000000 cm then

3 hectare contains 3000000 cm .

GIVEN : On 1 day of rainfall 12 cm of rainfall occur.

T/F : How many days or years it will take to occur 3 hectares of rainfall ?

SOLUTION : If we devide 3000000 cm by 12 cm then we will get the number of days for 3 hectare of rainfall that is = 250000 days.

If we again divide 250000 days by 12 then we will get the number of years for 3 hectare of rainfall that is

= 20833.333333333 years as 1 year contains 12 months .
