How many cups are in 3 gallons?

cups

The number of cups that corresponds to three gallons is:

48 cups.

Step-by-step explanation:

Since you have not provided a specific unit conversion within the text, I suppose it should be the normal conversion between a North American cup and a gallon in which:

1 gallon = 16 cups

Therefore, taking into account this unit conversion, to identify the number of cups to which 3 gallons correspond, the following is calculated:

3 gallons = 16 * 3 = 48 cups.
