A tank, 1.4 m long, 0.8 m wide and 0.5 m deep, is full of water. The water leaks at a rate of 40 cL per minute. After how long will the tank be empty?
volume = (1.4)(.8)(.5) m^3
= .56 m^3
= 560 L of water , 1 m^3 holds 1000 L
leak is 40 cl or .4 L/min ( 100 cl = 1 L)
number of minutes to drain = 560/.4 =1400 minutes
or 23 hrs, and 20 minutes
