Q18 of 24 Page 236

Rainfall recorded on a certain day was 5 cm. Find the volume of water that fell on a 2-hectare field.

Since 1 hectare = 10000 m2


Area of field = 2 hectare = 20000 m2


Recorded rainfall = 5 cm = 0.05m


Volume of water fell = area of field × recorded rainfall


= 20000 × 0.05


= 1000


So, volume of water that fell is 1000m3
