The weight of the girl is irrelevant for determining the amount of water displaced for her to float. In order to float, the girl needs to displace her weight in water, regardless of what that weight is. Since the weight of an object is equal to the weight of the water it displaces, the girl weighing 600N would need to displace at least 600N of water to float.
A girl weighing 600N is about 60kg, and a human body is covered in about 70 -80% water, hence the water displacement of that girl in order to float would be 75/100* 60 = 45L of water.

How much water must a ship displace in order to float?
A ship must displace an amount of water equal to its own weight in order to float. This principle, known as Archimedes' Principle, states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
Why must water be displaced in order for a system to float?
Water must be displaced in order for a system to float because of Archimedes' principle, which states that the upward buoyant force on an object is equal to the weight of the water displaced by the object. This buoyant force helps support the weight of the object, allowing it to float. If the object does not displace enough water to create an upward buoyant force equal to its weight, it will sink.
What needs to be equal in order for an object to float in water?
The weight of the object must be equal to the weight of the water it displaces in order for the object to float in water. This is known as Archimedes' principle. If the object is less dense than water, it will float; if it is more dense, it will sink.
What does an objects density have to be in order to float in water?
An object must have a density lower than that of water (approximately 1 g/cm3) to float in water. This means the object will displace an amount of water equal to its weight.
Do gravity cause things to float?
No, gravity is responsible for pulling objects towards the center of the Earth. In order for things to float, they need to displace enough water or air to create an upward buoyant force that balances the downward gravitational force, allowing them to stay on the surface of the water or air.

What does density have to do with the ability to float?
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
What should be the height of a girl weighing about 70 kilos?
A height for a girl weighing 70 kilos (around 154 pounds) should be around 5'7" and 5'9" in order to be considered healthy.

What is the weight of water displaced by a massless balloon?
No real object is massless. Even a balloon has the mass of the balloon plus the mass of the entrained gas.But if the buoyancy of the entrained gas (hydrogen, helium) allows the balloon to float away, then it will displace no water. Even so, it still has mass.
what is the value of 7 in 36.7?
A girl weighing 600N is about 60kg, and a human body is covered in about 70 -80% water, hence the water displacement of that girl in order to float would be 75/100* 60 = 45L of water.
What density does an object have to have to float in alcohol?
For an object to float in alcohol, its density must be lower than that of alcohol, which is around 0.79 g/cm³. This means the object must have a density less than 0.79 g/cm³ to displace enough alcohol to create buoyancy and float.
