* 1 cup = 0.25 quarts

* 1 pint = 0.5 quarts

* 1 quart = 0.25 gallons

Let's calculate the total gallons:

* 1 cup: 0.25 quarts * 0.25 gallons/quart = 0.0625 gallons

* 1 pint: 0.5 quarts * 0.25 gallons/quart = 0.125 gallons

* 1 quart: 0.25 gallons

Therefore, 1 cup, 1 pint, and 1 quart equal a total of 0.0625 gallons + 0.125 gallons + 0.25 gallons = 0.4375 gallons.
