To calculate the density of an object using Archimedes' principle, follow the given instructions:
Measure the object's mass in the air (ma) and when it is completely submerged in water (mw).
Calculate the loss in mass (ma - mw), which is also the mass of displaced water.
Determine the volume of displaced water by dividing the mass of displaced water by the density of water, i.e., 1000 kg/m3. This value is also the volume of the object.
Find out the object's density by dividing its mass by volume.
