Question

The rainfall recorded on a certain day was 8 cm. Find the volume of water (in litres)that fell on a 4 hectare field.

Answer 1

1 hectare =100000000cm
Rainfall recorded=8cm
.:.Volume=8x100000000
=800000000cubic centimetres

Answer 2

Answer:

3200000 liters

Step-by-step explanation:

400,000,000 sq cm

Area of filed = 4 hectares

4 hectare = 400,000,000 sq cm

So, Area of filed = 400,000,000 sq cm

The rainfall recorded on a certain day was 8 cm.

The volume of water that fell on a 4 hectare field= $Area \times height$

                                                                                 =$400000000 \times 8$

                                                                                 =$3200000000 cm^3$

1000 cubic cm = 1 liter

So, 1 cubic cm = 0.001 liters

So, 3200000000 = $0.001 \times 3200000000=3200000 liters$

Hence the volume of water (in litres)that fell on a 4 hectare field is 3200000 liters
