Detailed explanation-1: -Archimedes was well known for his inventions and scientific discoveries. The most famous of these were the Archimedes’ Screw (a device for raising water that is still used in crop irrigation and sewage treatment plants today) and Archimedes’ principle of buoyancy.
Detailed explanation-2: -He dropped the gold into a bowl filled to the brim with water and measured the volume of water that spilled out. Then he did the same thing with the piece of silver. Although both metals had the same mass, the silver had a larger volume; therefore, it displaced more water than did the gold.
Detailed explanation-3: -That Archimedes discovered his principle when he saw the water in his bathtub rise as he got in and that he rushed out naked shouting “Eureka!” (“I have found it!”) is believed to be a later embellishment to the story. Learn more about the life of Archimedes.
