Is it true that an object floats in water when its average density is lower than the density of water, about 1 gram per cubic centimeter, regardless of whether it is hollow or solid, according to Archimedes' principle?
Unclear. The retrieved sources restate Archimedes' principle as buoyant force equalling the weight of displaced fluid and give examples of floating objects, but none states the specific criterion that an object floats when its average density is below water's density regardless of being hollow or solid.
