What is the equivalent volume in gallons for 16.66 pounds of water?

• A. 1.5 Gallons
• B. 2.0 Gallons
• C. 3.0 Gallons
• D. 4.0 Gallons

Answer: (B)

To determine the equivalent volume in gallons for 16.66 pounds of water, it is essential to understand the relationship between weight and volume for water. Water has a density of approximately 8.34 pounds per gallon at its maximum density (around 39 degrees Fahrenheit).

To convert 16.66 pounds into gallons, you can use the formula:

Volume (gallons) = Weight (pounds) / Density (pounds per gallon)

By plugging in the values:

Volume = 16.66 pounds / 8.34 pounds per gallon ≈ 2.0 gallons

This calculation indicates that 16.66 pounds of water is equivalent to approximately 2.0 gallons. Recognizing this relationship and using the correct density is crucial in ensuring accurate conversions between weight and volume, especially in contexts related to fire service and water usage. Therefore, the correct answer reflects the proper understanding of water density and its implications in practical scenarios.
