# How many cubic feet of water are in a gallon?

#### Understand the Problem

The question is asking for a conversion factor between gallons and cubic feet, specifically how many cubic feet are equivalent to one gallon of water.

0.13368 cubic feet

The final answer is approximately 0.13368 cubic feet per gallon

#### Steps to Solve

1. Understand the relationship between gallons and cubic feet

We know that 1 gallon of water is commonly understood to be 231 cubic inches.

2. Convert cubic inches to cubic feet

There are 12 inches in a foot, so there are (12 \times 12 \times 12 = 1728) cubic inches in a cubic foot.

3. Set up the conversion factor

Since 1 gallon is 231 cubic inches, we can convert this to cubic feet by dividing by the number of cubic inches in a cubic foot:

$$\frac{231 \text{ cubic inches}}{1728 \text{ cubic inches/cubic foot}}$$

4. Calculate the result

Simplify the fraction or use a calculator to find the final answer:

$$\frac{231}{1728} \approx 0.13368$$ cubic feet

The final answer is approximately 0.13368 cubic feet per gallon
