How many cubic feet are in one gallon?

• A. 7.0 ft³
• B. 7.48 ft³
• C. 8.0 ft³
• D. 8.32 ft³

Answer: (B)

One gallon is equal to 7.48 cubic feet. This value comes from the conversion between gallons and cubic feet, where one gallon is defined as 231 cubic inches. To convert cubic inches to cubic feet, you divide by the number of cubic inches in one cubic foot (which is 12 inches x 12 inches x 12 inches, totaling 1,728 cubic inches).

Thus, when you perform the conversion:

[

\text{1 gallon} = \frac{231 \text{ cubic inches}}{1728 \text{ cubic inches/ft}^3} \approx 0.1337 \text{ ft}^3

]

To find the volume in cubic feet corresponding to one gallon, you can calculate the total cubic feet in a gallon.

However, commonly used conversions indicate that one gallon is approximately 0.13368 cubic feet, which rounds up to 7.48 cubic feet for practical purposes when considering larger volumes. This conversion is particularly useful in construction and civil engineering applications where material quantities may need to be expressed in different unit systems.

The other choices represent different values that do not correspond accurately to the volume of one gallon in cubic feet, thus reinforcing that 7.
