Archimedes came across concept of density - that is MASS divided by VOLUME. For each substance this ratio is different but a CONSTANT for that substance. Thus the mass you are dealing with is irrelevant if the crown had the same ratio as the piece of pure gold then the crown was pure god, if it did not then the crown was not gold.
Density was discovered by the Greek philosopher Archimedes around 250 BC. He realized that the buoyant force exerted by a fluid on an object could be used to determine the object's volume and, by extension, its density. This led to the development of the concept of density as mass per unit volume.
First, measure the mass of the water in the bathtub using a scale. Next, immerse yourself completely in the water and measure the increase in water level using a measuring cup. This increase in volume of water displaced is equal to your body volume. Finally, apply Archimedes' principle which states that the buoyant force acting on an object is equal to the weight of the water displaced, to calculate your mass.
That was Léon Foucault, in 1851.
The purity is determined by chemical analysis.
The determination is by chemical analysis.

You could determine whether the rock cooled underground or above the surface.
Climate, location and resources.

Archimedes didn't go to preschool. There was no education system. If you were rich you could pay a tutor to educate your child.
As far as I know, it was Archimedes..................... but I could be wrong.
so i could use it later in world history
You could say that, but there weren't as much records about his family.
Archimedes would have used the principle of displacement to compare the volume of the crown to the volume of the pure gold piece. If the volumes were equal, then the crown is pure gold. If the crown had a higher volume, it would mean that it was mixed with another material, making it less dense than pure gold.
1.5 + 0.5 + 1 = 3 You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
Archimedes, a Greek mathematician and inventor, is credited with discovering the principle of buoyancy. He made this discovery while in a bath, noting the water displacement when he got in. This principle is known as Archimedes' principle.
Archimedes had several inventions to defend Syracuse, including walls that could shoot arrows. The most famous of these inventions was the Archimedes Claw; a device to lift attacking Roman warships out of the water. No one today has been able to figure out how this device worked.
