62.4
The weight of water is about 62.4 pounds per cubic foot. This value is commonly used in engineering and construction to calculate the load of water in various structures, such as pipelines, tanks, and dams.
One cubic foot of water weighs about 62.4 pounds.
A cubic foot of water weighs aprox. 62.42796 pounds, 28316.847 grams, or 28.316847 kilograms. Here is some additional information from http://ga.water.usgs.gov/edu/waterproperties.html * Weight: 62.416 pounds per cubic foot at 32°F * Weight: 61.998 pounds per cubic foot at 100°F * Weight: 8.33 pounds/gallon, 0.036 pounds/cubic inch * Weight: 1679.616 pounds/cubic yard, based on 0.036 pounds/cubic inch * Density: 1 gram per cubic centimeter (cc) at 39.2°F, 0.95865 gram per cc at 212°F
The weight of a cubic foot (cf) varies depending on the material. For example, a cubic foot of water weighs about 62.4 pounds. However, a cubic foot of air has a negligible weight.
The weight of water is approximately 62.4 pounds per cubic foot. Therefore, 22.75 cubic feet of water would weigh approximately 1422 pounds.
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.
Water weighs 62.42 pounds per cubic foot which is 561.78 pounds per cubic yard. Thus 200 cubic yards of water weighs 112,356 pounds.
A square yard is a measurement in 2 dimensions, length and width. Since there is no depth measurement in a square yard, therefore, a square yard of water has no weight. However, "...a cubic yard is 27 cubic feet, and a cubic foot of water weighs about 62.4 pounds, so 62.4 x 27 gives you...about 1685 pounds." (http://saluqi.home.netcom.com/ticklinx1.htm)
The sinking depth of a cubic foot weighing 10 pounds will depend on the density of the material it is floating in. If the density of the material is less than the density of the cubic foot, it will float. However, if the density of the material is greater, it will sink until the weight of the displaced material equals the weight of the cubic foot.
Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.
The weight of 1 cubic foot of aluminum is approximately 168.5 pounds.
1 foot = 30.48 cm, cube this for volume in cu cm = 28316.85 cu cm, weight at 1 g / cu cm (density of water) = 28316.85 grams = 28.31685 kgs, then * 2.2046 ( kgs > pounds) = 62.43 pounds
