Who was Archimedes.
Archimedes
The concept of density was invented, not discovered. It was invented by thinkers who needed a way to describe the weight of a substance that depends only on the substance, and not on how much of it you have.
Eureka! Archimedes may have the answer. Sink your solid in a measuring cylinder,or the equivalent, and measure the volume of the displacement. Archimedes indeed discovered the practical solution. The formulas for almost all theoretical solids were figured out by the time of Johan Kepler. It was Isaac Newton and/or Goffreid Leibnetz that finally came up with integral calculus that takes care of absolutely everything.
Not a theory, They discovered a branch of math called calculus.
Archimedes discovered the concept of gravity with his levers and pulleys, his theory of displacement and invented the screw.
He discovered it.
Archimedes
If you are talking about water displacement, it is the Greek philosopher Archimedes who is credited with that.
Archimedes contributed the theory of buoyancy, which is significant because it allows us to measure an object's weight by its displacement in water, density, displacement, and the buoyancy of the liquid in which the object is acting.

A good example of a Greek philosopher is Archimedes who discovered displacement (when you sit in a full bath tub it overflows).
Water displacement is used to find the volume of irregular solids as discovered by Archimedes
Archimedes
Who was Archimedes.
No. The answer to this multiple-choice question is that he discovered "displacement", famously seeing water spill out of his filled bathtub when he got into it. ("Eureka!")
Archimedes (287-212 BC) was a Greek scientist in the city of Syracuse in Sicily (which fell to Rome and became part of Italy). According to the famous legend, he discovered the theory of displacement when water overflowed as he entered a full bath.
