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)
That is an unanserable question. Square foot means an area and for a weight you need at least a volume.
To have weight it must also be a three dimensional unit, things don't have weight in the flatlands. A cubic foot of water weighs 62.42796 Pounds. A cube is the three dimensional version of a two dimensional square, a foot of depth being the difference between a square and a cube.
1 Cubic feet = 62.4269107 Pounds. 1 Cubic inches = 0.0361267 Pounds found at onlineconversion.com
That's the same as saying one cubic foot of water, and it weighs 7.481 pounds.
Wrong. 7.5 gals of water in a cubic foot weighing 62.4 pounds.

Water has density and weight. The deeper you dive the more water you have pushing against your body. Think of it like this young padawans: You place a book on your head, no big deal. For every foot that your imagination takes you deeper on a dive add one book. Is that stack of books getting heavy yet? Well if you imagined yourself diving to 130' (FSW) then that stack of books would have weighed in at 130' x .445lbsPerSqInch (book/foot) = 57.85 lbs. 130 being the depth of water in feet salt water (FSW), .445 being the weight of one foot of salt water (one book). The answer is the weight of water (books) measured over the area of one square inch. When you dive, you have the weight of all of the water over you, plus the weight of the earths atmosphere exerting pressure on you (the atmosphere is often neglected, but is of importance). The example of the books that I used is a little innaccurate though. In that example the weight is only being placed on one square inch of your head. In diving however, that force would exist over every square inch of a divers body. You can see how these numbers can add up, and you would think would severely limit the diver. However the body is primarily fluid which is not compressable. Those parts of the body which are compressable (Sinuses, Middle Ear, Respiratory tract, Lungs) are easily equalized with ambient pressure through training and or past experience. If you are wondering how I know what one foot of sea water weighs per square inc h, simply multiply .445lbs (one foot SeaH2o) times 144 (inches in a square foot)= 64 lbs which is the equivalent to the weight of one Cubic foot (ft3) of sea water.
approx. 3,8 kg.
Whether an object will float or sink in water will depend on its volume and weight. If the weight of the displaced water is more than that of the body, the body will float. On the other hand if the weight is the displaced water is less than that of the body, the body will sink. Again if both of them are equal, the body will partially sink. Sea water contains salt. So its density is more and consequently, the weight of the sea water is more. So there is more chance of a ship to float in sea water than in river water. ADD: It depends on the density of the object. If an object is denser than water, it will sink. If it is less dense than water, it will float.
Ethiopia consists of about 1,277,000 Square kilometers of land mass and 7,500 Square kilometers of surface water with zero sea front.
The Caspian Sea is the Worlds largest salt-water lake.
One cubic foot of sea water contains about 7.5 gallons.
About 2.2 pounds of salt in a cubic foot of sea water. There are about 7.48 gallons in a cubic foot and sea water weighs about 8.5 pounds per gallon (63.58 pounds). Sea water is about 3.5 % salt (usually reported as 35 ppt or parts per thousand). So 63.58 x .035 = 2.2 pounds of salt.
Technically, neither. They are both the same weight but not exactly weigh anything as water can alter our weight.
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.

The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
14.7 pounds per square inch at sea level.
The Caspian Sea is the largest enclosed body of water at 143,244 square miles.
Does not really matter. As long as it is over a foot.
