What is the weight of one square foot of water?

Answer 1

The weight of one square foot of water is zero pounds. A square foot is a measurement of area, not volume. Since a square foot has no height, it is not possible to fit even a single hydrogen atom inside a square foot.

The weight of a cubic foot of water (a cube with each side equal to one foot) is about 62.42 pounds. The reason that I saw "about" is because the density of water changes according to its temperature, so that a cubic foot of water at 32 degrees Fahrenheit will weigh 62.42 pounds, but at 212 degrees Fahrenheit a cubic foot of water weighs 59.83 pounds.
