Question

if the rainfall on a certain day was 5cm, how many litres of water fell on 5 hectares field on that day
​

Answer 1

Answer:

=> Rainfall on a certain day = 5 cm = 5/100 m

=>Area of land = 1 hectares = 10000 m²

Volume of rain that falls on 1 hectare land => (10000 × 5/100) m³ = 500 m³

=>1 m³ = 1000 litres

so, 500 m³ = (500 × 1000) litres = 500000 litres.

Key concept

Hectares

Hectares- A hectare is a unit of area equal to 10,000 square meters . it is usually used to measure land .

Answer 2

Answer:

2500000 L water fell on that day

Step-by-step explanation:

We Have :-

Rainfall on certain day = 5cm

5 Hectares of field

To Find :-

Volume of Rain in Litres

Solution :-

1 hectare = 10000m²

1cm = 0.01m

5cm = 0.05m

Volume of water is depth a area

Volume = 0.05m x 5 x 10000m² = 2500m³

Converting to litres.

1m³ = 1000L

2500m³ = 2500000L

2500000 L water fell on that day
