How deep is the pool if there are 2025 hectoliters of water and the bottom dimensions are a = 15 meters b = 7.5 meters, and the water level is up to 9/10 (nine-tenths) of height?

Correct answer:

h =  2 m

Step-by-step explanation:

V=2025 hl m3=2025:10  m3=202.5 m3 a=15 m b=7.5 m S=a b=15 7.5=2225=112.5 m2  c=V/S=2405/2225=2405:2225=2405 2252=2 225405 2=450810=59=1.8 m c = 109 h  h=910 c=910 59=9 510 9=4590=2 m
