a rectangular tank is 5 meters long 1.5 meters wide and 3 meters high. The tank is filled with water at a rate of 0.06m3 per minute. Calculate the time, in hours, needed to fill the tank

6.25 hours

Step-by-step explanation:

The volume (V) of the tank is calculated as

V = lbh (l is length, b is width and h is height), thus

V = 5 * 1.5 * 3 = 22.5 m³

Divide V by rate for time in minutes

Time = 22.5 : 0.06 = 375 minutes

Divide minutes by 60 to convert to hours, that is

Time to fill tank = 375 : 60 = 6.25 hours
