A swimming pool is 200 m×50 m and has an average depth of 2 m. By the end of a summer day, the water level drops by 2 cm. How many cubic metres of water is lost on the day?
Dimensions of swimming pool are 200 m×50 m
Area of the swimming pool=200×50
=10000 m2
Average depth of the swimming pool =2 m
At the end of summer day the water level drops by 2 cm=0.02 [Since,[1 cm=1100m]]
Volume of water lost=Area × height reduced.
=10000×0.02
=200 m3
