Firstly weigh it. Then dunk it in water to see how much water is displaced. This gives you the volume. The density is then the mass / volume.
Units are most often kg.m^-3

To calculate the density of a solid object, you divide the object's mass by its volume. The formula for density is density = mass / volume. Mass is typically measured in grams or kilograms, and volume is usually measured in cubic centimeters or cubic meters.
To find the density of a solid object, you need to divide the object's mass by its volume. The formula for density is: Density Mass / Volume. This calculation will give you the amount of mass in a given volume of the object, which is a measure of how tightly packed the particles are within the object.
It is difficult to get the density of a crushed solid because the crushing process can alter the object's original structure, making it harder to calculate an accurate volume. Additionally, the irregular shapes of the crushed particles can lead to inconsistencies in the measured density.
If the solid is not completely submerged in the water, the volume of water displaced will be underestimated. This error will lead to a lower apparent volume, resulting in a higher reported density of the solid than the true value.
The density of a hollow object would be lower compared to a solid object of the same material because the total mass is distributed over a larger volume due to the empty space inside the hollow object.
