Question

A swiming pool is 200m by 50m and has an average depth is 2m. By the end of the a summer day, the water level drops 2cm.how many cubic meter of water is lost at the end of the day?

Answer 1

Area of swimming pool = 200×50 = 10000 m^2

drop in water level = 2cm = 0.02m

Volume of water lost = area × height reduced = 10000 × 0.02 = 200 m^3

Thus water lost is 200 cubic meter

Answer 2

200 $m^3$ of water is lost at the end of the day

Step-by-step explanation:

Given:

A swimming pool is 200 m by 50 m and has an average depth is 2 m. By the end of the a summer day, the water level drops 2 cm.

How many cubic meter of water is lost at the end of the day

Solution:

Area of the swimming pool = 200 $\times$ 50 = 10000 $m^2$

Drop in water level = 2 cm = 0.02 m

Volume of water lost = Area\Times height reduced

= 10000 $\times$ 0.02 = 200 $m^3$
