Answer :

To determine how many ounces are in 3 gallons, we need to know the conversion factor between gallons and ounces. Specifically, 1 gallon is equal to 128 ounces.

Here's how you can calculate it step by step:

1. Identify the conversion rate:
- 1 gallon = 128 ounces.

2. Calculate the total ounces for 3 gallons:
- If 1 gallon is 128 ounces, then to find the equivalent of 3 gallons in ounces, you multiply the number of gallons (3) by the number of ounces in one gallon (128).

3. Perform the multiplication:
- 3 gallons × 128 ounces/gallon = 384 ounces.

Therefore, 3 gallons is equal to 384 ounces.

The correct answer is A 384 oz.
