How much does a cubic foot of water weigh?

A cubic foot of water weighs approximately 62.38 pounds. This weight is based on the fact that water has a density of about 62.4 pounds per cubic foot at a temperature of 39.2°F, which is its maximum density. The figure of 8.34 pounds often applies to a gallon of water; specifically, there are 7.48 gallons in a cubic foot, leading to the weight of one gallon of water being approximately 8.34 pounds. However, when the question specifically asks for the weight of a cubic foot, the correct weight is derived from understanding the volume and density relationship, indicating that the conversion involving gallons does not apply when calculating the weight of a cubic foot directly.
