When a person floats in water, they displace an amount of water equal to their own weight. This principle is known as Archimedes' principle.
In your scenario, the person weighs 200 pounds. To determine the weight of the water displaced, we need to convert pounds to a unit of mass, such as kilograms, because the weight of an object is typically measured in mass units.
Assuming 1 pound is approximately equal to 0.4536 kilograms, we can convert the person's weight:
Weight in kilograms = 200 pounds * 0.4536 kilograms/pound
Weight in kilograms = 90.72 kilograms (approximately)
According to Archimedes' principle, the weight of the water displaced by the person floating will be equal to their total weight. Therefore, the weight of the water displaced in this case is approximately 90.72 kilograms.
