Question

which is a better estimate for the volume of a cream cheese carton? 3 gallons 3 fluid ounces

Explanation:

A gallon is a very large unit of volume (1 gallon = 128 fluid ounces), which is far too big for a typical cream cheese carton. A standard cream cheese carton is small, so 3 fluid ounces is a reasonable estimate.

Answer:

3 fluid ounces
