Assume that when you take a bath, you fill a tub to the halfway point. The tub measures 5 feet by 3 feet by 2.8 feet. When you
take a shower, you use a shower head with a flow rate of 1.52 gallons per minute, and you typically spend 12 minutes in the shower. There are 7.5 gallons in one cubic foot.
Total water used while taking a bath is half the volume of water in tub. Volume of water used=(volume)/2 =(5×3×2.8)/2 =42/2 =21 cubic feet
Total amount of water used while taking a shower will be given by: Total amount of water=rate×time =1.52×12 =18.24 gallons Thus amount of water in cubic feet if there are 7.5 gallons in 1 cubic foot will be: amount=18.24/7.5=2.432 cubic feet.
Therefore the conclusion is, the person is using more water in bathing than shower.
