Proposed by Archimedes in 250 BC
If the weight of the water displaced by an object > weight of the object, object floats.
Water displaced by a hollow object and a solid object will be the same.
But hollow object is lighter so it will float.
This is why boats float and solid cubes drown.
It is a fundamental principle in fluid mechanics.
“Eureka” was uttered by Archimedes when he discovered it.
