Answer:
Explanation:
The tub measures 5 feet long, 2.5
feet wide, and 1.5 feet tall. The volume of the tub would be
Volume = 5 × 2.5 × 1.5 = 18.75ft²
There are 7.5 gallons in one cubic foot of water. This means that 18.75ft² of water would be
18.75 × 7.5 = 140.625 gallons of water.
When you take a bath, you fill a tub to the halfway point. This means that the volume of water that you use when you bath is
140.625/2 = 70.3125 gallons
When you take a shower, you use a shower head with a flow rate of 2.1 gallons per minute. If you shower for 15 minutes, the volume of water used would be
2.1 × 15 = 31.5 gallons
Therefore, you use more water taking a bath.
