How many square inches are in 1 gallon?

1. 72 sq in

2. 100 sq in

3. 144 sq in

4. 200 sq in

The correct answer is: 144 sq in

To determine how many square inches are in one gallon, it's important to clarify that the question seems to be mixing two different measurements: gallons measure volume, while square inches measure area. However, if we assume that the question is referring to a conversion related to the use of gallons in a context where surface area is circumstantially relevant, we can provide context. One gallon is equal to 231 cubic inches. The conversion to square inches does not apply directly since it is not possible to convert a unit of volume to a unit of area without additional information, such as depth or height, which is not specified here. The answer provided indicates a misunderstanding of the nature of the measurements involved. For clarity, to fully understand how these measurements relate, one would typically need more context about what is being measured or applied in terms of the gallon—like the surface area of paint coverage or some other related measurement in context. When selecting options, it is crucial to understand the properties of the units being discussed to make an informed decision. In this case, understanding the conversion factor for volume to area without relating it to a specific context might lead one to interpret the options differently.
