The weight of one cubic foot of water is approximately 62.4 pounds at standard temperature and pressure.
To explain further, water has a density of about 62.4 pounds per cubic foot. This means that if you were to fill a container that has a volume of one cubic foot with water, the total weight of the water in that container would be around 62.4 pounds. This value can slightly vary with changes in temperature and impurities in the water, but under normal conditions, you can rely on this figure for most practical purposes.
