You need to put it into a container or other measuring object and use the water displacement method. This means that you put water into the container and when the object is placed inside, you take the difference between the height of the water before and the height of the water afterward. This is the volume of the object.
Take an amount of water of which you know the volume. Drop the object in the water. Find the difference
Use volume displacement method.
It is used to find the volume of an irregularly shaped object. An object dropped into a volume of water will displace an equal volume of water.
When you are trying to find the volume of an irregularly shaped object.
It is the displacement method.
The volume of an irregularly shaped solid can be measured by placing the solid in a known quantity of water in a container with measurement markings. Take the new volume and find the difference between this and the old volume. This is the volume of your irregularly shaped solid.
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
Using a graduated beaker, add water sufficent to totally immerse the object. Note the initial volume of the water without the object.
Half fill a graduated glass beaker with water and note the level. Place irregularly shaped object into the beaker. Note the new level. The difference between the two levels is the volume of the object. cw: OK, that method works for objects that don't get wet -- like steel. Tissue paper would not be a good candidate. Also, if the object floats, you have to submerge the object.
break it up into pieces you know how to find the volume of
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. The difference between the before and after levels of the liquid is the volume of an immersed object.
The easiest way is to place the object in a graduated beaker of water, and see how much the water rises when you put it in. Archimedes Principle says that the volume of the object is the same as the water displaced from the beaker.
