King Hiero asked a crown maker to make him a golden crown.
At first, he was very happy with it.
This problem seems difficult to solve.
Archimedes was certain that it’s not completely made of gold.
It is a good crown, isn’t it
However, he began to doubt that it was a real golden crown.
He then sent the crown maker to prison.
Archimedes was still thinking about this problem as he filled his bath with water.
First he weighted the crown and asked the king for some gold of the same weight.
This time, even more water ran into the bowl.
