How many gallons of water are equivalent to 90 lbs?

To determine how many gallons of water are equivalent to 90 pounds, it's essential to understand the basic conversion between weight and volume for water. The density of water is approximately 8.34 pounds per gallon.

To find the volume in gallons from the weight in pounds, you can use the formula:

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

Using the values provided:

Volume = 90 lbs / 8.34 lbs/gallon ≈ 10.80 gallons.

This calculation shows that 90 pounds of water is approximately 10.8 gallons, which aligns with the correct answer.

This method highlights the importance of understanding the relationship between weight and volume, particularly for substances with known densities, such as water. It's crucial to remember that this specific density applies at standard temperature and pressure conditions when dealing with water in practical applications.
