Question

rainfall on a certain day 9cm. how many litres of water fell on 5 hectares of land

Answer 1

Answer:

area of land =1 hectare= 10^8 cm square=100000000

height of rainfall=5 cm

thus amount of rainfall=5* 100000000

since , 1 meter cube =10^6 cm cube+1000000 cm cube

so, 5*100000000/1000000 m cube

=5*100 m cube

=500 m cube

as 1 m cube=1000 liters

500 m cube= 500*1000 liters

=500000 liters

so amount of rainfall that day is 500000 liters
