The two things that water displacement techniques can be used to calculate are:
1. Volume of an object: By placing the object in a container of water and measuring the increase in water level, one can calculate the volume of the object using the formula: Volume = Final water level - Initial water level.
2. Density of an object: By measuring the weight of the object and calculating its volume using water displacement, one can determine the density of the object using the formula: Density = Mass / Volume. This is because the density of an object is its mass per unit volume.
The image below illustrates Archimedes' principle of water displacement. Water displacement techniques have been used for generations to calculate/determine TWO things.
