How do you use the displacement method to find volume?

Answer 1

The displacement method is a method for measuring the volume of a solid. The solid is immersed in liquid and the level of the liquid before it is immersed is subtracted from the level of the liquid after it is immersed to get the volume of the solid.

Answer 2

L X W X H Length times width times height. For an odd object, put an object in a graduated cylinder, measure the level before and after the object was put in, subtract the two quantities, and convert mL to cm3 (ex: 1 mL = 1 cm3)

Answer 3

This method only works for solids, and obviously if you pour a liquid into another liquid to test it's volume, you will lose the liquid.

First you put a general amount of water into a graduated cylinder, or a cylinder with lines marking the volume. I would recommend using about 10 mmL of water.

Next, drop your solid into the graduated cylinder. Observe what the water line has risen to be. For example, the water line begins at 10 mmL, and after you drop your solid in, it has risen to be 25 mmL. You then subtract the old volume from the new, and the difference is your solid's volume. In the example, you would subtract 10 from 25 to get 15.

Answer 4

According to Archimades' principal, any object or part of the obect that is submerges will be the same volume as the water it displaces. So for example. You put a grape in a full cup of water. Let's say the water that flows out goes into a measuring cup. Now let's say the displaced water is about 10 mL (ten milliliters). Then the grape's volume would be 10cm^3 (ten centimeters cubed). (Since 1 mL= 1 cm^3) This is also the method of finding the volume of irregular shaped objects.
