Floating in water is an interesting phenomenon that was discovered by Archimedes around 246 BC. He analysed several factors governing the floatation and attributed it to the relative density of the solid and the volume of the solid. For instance, a box made of iron will sink whatever its shape, size, or design, whereas big ships made up of wood float in water. So, the floatation depends on the material. Similarly, floatation depends on the volume of the object as well. If the object has more volume, it is more likely to float.
