You need to do the water displacement method. The water displacement needs a graduated cylinder and water.
Get a sample of the metal. Use a scale to find its mass. If it is shape is that of a rectangular solid (box) measure length, width, and height and multiply to find volume. If it is irregularly shaped, use the water displacement method to find its volume. Divide the mass by the volume to get the density.
The water displacement in water can be calculated using Archimedes' principle. It states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. So, to calculate water displacement, you would need to determine the weight of the object and divide it by the density of water (which is approximately 1000 kg/m^3).
He figured out the displacement method.
You will need the mass and volume of the block. To find mass, use an electronic balance. To find volume, use length x breadth x height. For irregular solid, use the water displacement method. The density is mass divided by volume.
density = mass/volume Determine the volume of the screw by using the water displacement method (see related link below). Determine the mass of the screw on a balance or scale. Divide the mass by the volume, and that will be the density.
They are both the same. displacement method is another name for Archimedes' principle
I think to the helium pycnometry.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.

The displacement method is used to determine volume. However, if you know the density, the displacement test can give volume, which is used to work out mass by the formula m = dV
Water Displacement Method?
This method is used for the determination of True density of the particles i.e Grains, any liquid substance etc. True density refers the density of the material with compaction. The value is always higher than Bulk density.
Find the mass using a scale. Find the volume by the water displacement method. Divide mass by volume and that equals density.
First 'weigh" the ojbect on a scale. this gives the mass. 2nd use the water displacement method to find the volume. Then divide Density = mass / volume.
The Liquid Displacement Method involves putting an object into a container filled with water. A measurement is then taken of how much volume of water has been displaced. This measurement can then be used to calculate the volume of the object displacing the water.
