A residential

A residential colony has a population of 5400, and 60 liters of water is required per person per day. The effective utilization of rainwater constructed a water reservoir measuring 48m × 27m × 25m to collect the rainwater. For how many days, the water of this tank is sufficient? If during rain the height of water level is 5 m?

Correct answer:

d1 =  100 d
d2 =  20 d

Step-by-step explanation:

d=5400 60/1000=324 m3/d V1=48 27 25=32400 m3 d1=V1/d=32400/324=100 d
V2=48 27 5=6480 m3 d2=V2/d=6480/324=20 d
