Hiero II of Syracuse wanted to have a crown of pure gold. The goldsmith cheated and removed the pure gold and added the weight in silver. When Archimedes understood this, he put the gold and silver crown in the water and then he understood that the goldsmith had cheated Hiero II.

Equipment for weighing objects already existed at the time, but Archimedes now was happy that he could also measure their volume!

Archimedes was from Greece. He was born in 287 BC and died in 212 BC at the age of 75.

Archimedes was one of the best maths professors and he was an engineer, too. He was killed by a Roman soldier during the siege of Syracuse.

Archimedes was the person who said the famous word “Eureka!”. He said that because he noticed that the water level rose when he was in the bath. Then he understood that the volume of the water was displaced.

He wrote the first books on flat geometry and maths. He also invented lots of war machines. He helped the whole world with his discoveries!
