How to Find Volume With Water Displacement Method

Science teaches us to think out of the box. So while others may only use water for drinking and bathing, we shall learn how to use it to find the volume of an object.

Note: Measuring flask measurements are in ml. Example 1
Example 2
Example 3
How to Find Density
Archimedes was able to calculate the density of the crown using the water displacement method. We too can calculate the density of any irregular object by using the steps given below. 1) Find the volume of the object as described in the previous section. 2) Use a weighing machine to find the mass of the object. Now, from the definition of density, we arrive at the following equation which can be used to calculate the density of the object:
Density = Mass ÷ Volume
For example, if the calculated volume of object is 4 ml. and its mass is 8 gm, then its density will be (8 ÷ 4) = 2 gm/ml
Thus Archimedes, over 2,000 years ago, came up with the water displacement method which could be used to find the volume of an irregular object. The invention of this method was a great achievement back then, and it is still relevant in modern times, owing to its simplicity and high degree of accuracy.
