Hectoliters 81834

They filled the 25m long, 15m wide swimming pool with water to a height of 80cm. How many hectoliters of water did they put in, and how long did it take for the pool to fill if 375 hectoliters flow in 1 hour?

Correct answer:

V =  3000 hl
t =  8 h

Step-by-step explanation:

a=25 m b=15 m c=80 cm m=80:100  m=0.8 m  V1=a b c=25 15 0.8=300 m3  V=V1 hl=V1 10  hl=300 10  hl=3000 hl=3000 hl
Q=375 hl/h  t=V/Q=3000/375=8 h
