Explanation Given: Tub has dimensions of 6 feet by 3 feet by 2.5 feet. Shower has a flow rate of 1.75 gallons per minute It takes 10 minutes to shower Each cubic foot has 7.5 gallons Formula used: a) Volume =Length x Height x Width b) Volume = Flow rate x time Calculation: a) Water quantity consumed can be estimated by evaluating the volume in each case. For bath, half of the tub is filled: Volume = 1 2 x Length x Height x Width=0 .5 x 6 x 3 x 2 .5=22 .5 cubic foot For Shower: Volume = Flow rate x time=1 .75 gallons minutee x cubic feet 7 .5 gallons x 10 minutes=2 ...
