Archimedes is an ancient Greek inventor and mathematician
you get volume by dividing mass by density or by achimedes/relative density method
Achimedes was born in Italy and stayed in Greece throughout his life, as far as I know.
There are many ways to find a Acimedes, but the fastest way is to go to ChrissyH's profile ( the top player on howrse ) She has one, and the link is on her page!
Archimedes' principle states that an object partially or fully submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. This principle can be used to calculate the buoyant force acting on an object in a fluid and determine if the object will float or sink.
Archimedes principle states that any immersed body in a fluid will experience a buoyant force which is equal to the weight of fluid displaced by it and always acts upwards through the centroid of displaced volume. Note that if the object weight less than the wieght of water it displaces, it will float. If it is heavier than the weight of water it displaces, it will sink but its apparent weight in water will be its in-air weight minus the weight of the water it displaces.
Greek nomads, having completely looted the area of mainland Greece, had to settle on the land and farm to get subsistence. The different tribes which took the limited farming areas between the mountains each set up a defensive fortress on a mountain which grew into a city, and so city-states were formed. Being great breeders, they overpopulated their limited land an sent out the surplus people to seize new land and form new cities for themselves. This was first to the east around the Aegean Sea, but later spread to the west as far as Sicily, Italy, North Africa and Spain, all up about two thousand independent ciy-states.
A ship floats because it displaces a volume of water equal to its weight, allowing it to stay afloat. The buoyant force exerted by the water supports the ship's weight, preventing it from sinking. The ship's design and shape also contribute to its ability to stay afloat by distributing the weight evenly and displacing water effectively.
Boats float because of buoyancy, which is a force that pushes upward on an object in a fluid (water) that is equal to the weight of the water displaced by the object. The shape of a boat's hull is designed to displace enough water to create buoyant force greater than the boat's weight, allowing it to float.
