Step 1: Fill a graduated cylinder with water
Step 2: Measure how much water is in the cylinder
Step 3: Place the cork in the water
Step 4: Measure the amount of water again
Step 5: Subtract amount of water without cork and amount of water with cork
regular- cork = volume of cork
This method is called water displacement.

No. This will give you volume. You cant tell density from that. Air in a balloon can give you the same result. Or even a piece of steel of the same mass.
Actually you can determine the density of a piece of cork using the displacement method because of the volume. Remember how D=M/V? After you weigh the piece of cork to find the mass, use the information you determined from the volume to get the density. (Use the equation as if that's not obvious.)
Density = Mass / Volume and the displacement of a liquid method states that whatever volume of liquid an object displaces, that is its volume. So if an object is floating, the volume of liquid that is displaced will be equal to the volume of the cork that is submerged.
the same as you measure the volume of a non-floating object: push it under water by pressure or just putting a heavy object on top, and then measure the amount of supplanted water minus the amount of water supplanted by the object you used to push the floating object down.
No, the water displacement method could not be used to determine the volume of a cork that floats on water. This method could not be used because the cork will not displace an accurate amount of water if it is not submerged.

I suppose you could try pushing a pin into the top of the cork and using that as a handle to force the cork down until completely, but only just, submerged.
Because the corks density is very low and it will float on top of the water
How do you measure the volume of a cork when it floats and doesn't sink?
yes, but you would have to subtract the air spaces of the sponge. After the sponge is wet, all the air spaces will be filled in by water, and you will receive incorrect information.
they are equal.
There are many ways to find the volume of irregular shapes, but the most commonly used method is Water Displacement.
They are equal.When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down.Note - relation between volume(v) mass(m) and density(d) : d = m/v
It is actually a means of finding the volume of an irregular shaped object. A graduated cylinder and a specific amount of water is used. Then the object is slid in. Water is measured and you figure out the difference of measures. Example: you start with 50 ml. than add the object. if it is now 25ml, the volume is 5
I don't see why measuring the volume of liquids using the Eureka can method. It is an indirect measure -- you displace water or some other fluid to measure a liquid? A direct tool, such as measuring beakers or cylinders with markings, is inexpensive and can measure volume adequately. Eureka cans are more for measuring the volume of solids, especially irregularly-shaped ones. ===================================
Yes
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.
Displacement method.... Is the method to find volume of an irregular object
The water displaced by the body is equal to its volume.
The volume of water displaced is equal to the volume of the object submerged into the water
Yes. The floating object is an addition to the mass system, even though it cannot displace its entire volume in the water.
Use the water displacement method
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
Fill a cup to the brim with water. Put egg in water (it should sink), capturing all of the overflow of water. Measure volume of water. This volume will match the egg's volume. Sinking objects displace volume, floating objects displace mass.
Displaced water method.
Treading water. Drown proofing is what the military teaches.
the water displacement method
Archimedes principle states that a floating body displaces its own weight of water. The density of the water is fixed so the volume displaced by a floating body is is the same for floating bodies of the same weight. The water level will still be delta h1 as the volume of the block is not relevant to the amount of water displaced.
