Archimedes and the golden crown

One day in ancient Greece, King Hiero asked a crown maker to make him a golden crown. At first, he was very1 with it.

"It's a nice crown, isn't it?" he asked his men. Later, however, he began to doubt2it was a real golden crown. "Is it made completely of gold?" he wondered. He sent it to Archimedes and asked him to find out the truth.

"This problem seems difficult to solve. What should I do?" thought Archimedes.

Archimedes was still thinking about this problem3he filled his bath with water. When he got into the bath, some water ran over.  

"That's it!" shouted Archimedes. "I know4 to solve the king's problem!"

Archimedes went straight to the palace to see the king. First, he5the crown and asked the king for some gold of the same weight.

Next, he put two pots into two big bowls and filled6pots with water. He put the gold into one pot, and some water ran into the bowl. Then he put the crown into7pot. This time, even more water ran into the bowl.

"Look at this," said Archimedes to King Hiero. "A crown8completely of gold displaces9water than a crown made of gold and another metal. This crown displaced more water than gold of the same weight, so I'm certain that it is not10made of gold. "

"The crown maker tricked me, didn't he? What a bad man he is!" shouted King Hiero. He then sent the crown maker to prison.
