He filled a bath half way with water then when he went in he found out that the water moved up, he wondered how that happened. So he started to study further into it....
You find the length and height of the shape, them you find the volume
You cannot find the volume of a square. You can find the volume of a cube, which is finding the length of one edge of the cube and taking that to the third power, or cubing it.
use the formula 4/3*π*radius3 to find the volume of a sphere.
The volume of a sphere is 4 / 3 * pi * r3
height*length*width = volume Divide both sides by length*width to find the height: height = volume divided by length*width
he find that the water was risen where he stared to put the person in.

Archimedes
215bc
He discovered that you have to find the volume, mass, and density of something
How? With his brain! That's how he answered it
He discovered the method to calculate the volume of a irregular object (rock).
Archimedes
Archimedes took a bowl full of water of known volume and then dipped the irregular shape body. Amount of water fall down is measured and is the volume of that body.
Water displacement is used to find the volume of irregular solids as discovered by Archimedes
Archimedes discovered that all substances have a unique density - the amount of mass contained in a fixed volume of the substance.
Presumably during his life time and the volume in cubic units = 4/3*pi*radius3
