Question

If the rainfall on a certain day was 5 cm. How many liters of water fill on 8 hectares field on that day?

Answer 1

One hectares= 10000 m²= 100000000 cm²
Area of field is 8 Hectare = 8*100000000=800000000 cm²
Volume of rain fall in the field = Area* 5 cm = 4000000000 cm²
                   one liter = 1000 cm²
Hence qty of water = 4000000000/1000=4000000 ltr
Field is filled with 4000000 liters of water.

Answer 2

Solution;

Find the capacity of bottle in 1 hectares?


Volume Of Water = Length×Breadth×Height

We know that:

Area = Length×Breadth

Height = 5 cm

1 Hectare = 100000000 cm 2



Volume = 100000000×5

= 500000000 cm³

1 m³ = 1000000 cm³

= 500000000 /1000000 = 500 m³

1 m³ = 1000 liters

500 m³ = 500,000 liters

Therefore, in 8 hectares = 5000000×8 => 4,000,000 litre
