Eureka!

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!
