Alternatively:
The simplest method, for objects that are insoluble in water and denser than water, is the displacement method. It may be possible to get around the problem of solubility or density by using a different fluid.
Otherwise, you will need to decompose the object into smaller units whose volume is regular, calculate the volume of each unit and add them together.
Yes--as long as they are homogeneous, too.
or in short we use WATER DISPLACEMENT METHOD
graduated cylinder
A balance is used to measure the mass of an irregularly shaped solid.
the water displacement method
yes you can use a balance to measure the volume of an irregular shaped solid.
Finding the center of gravity of an irregularly shaped object can be done using the plumb line method.
ways of locating center of gravity?
It depends on what the second method is!
Use volume displacement method.
break it up into pieces you know how to find the volume of
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
It is the displacement method.
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.
