How much does water weigh per cubic foot?

Water has a density of approximately 62.4 pounds per cubic foot at standard temperature and pressure. This value is crucial because it is often used in various calculations involving water content in engineering, environmental studies, and even in everyday tasks where water capacity is relevant.

Understanding the weight of water can help individuals comprehend how much water a given space can hold and how this weight can impact structures. For example, knowing that water weighs approximately 62.4 pounds per cubic foot is useful when calculating how much weight a swimming pool or large body of water puts on a foundation.

The other choices reflect values that do not align with the known weight of water. For instance, 60.4 pounds might mistakenly reflect a variation in temperature or impurities, while 23.8 pounds does not accurately represent any significant measurement associated with water in these contexts. Lastly, 78.9 pounds would be too high for a cubic foot of water, leading to misconceptions in the field. Thus, the correct understanding of water's weight at 62.4 pounds per cubic foot is essential for practical applications in various domains.
