Will an object with a density of 0.7 g 1 cm3 float or sink im water?

An object with a density of 0.7 g/cm³ will float in water, which has a density of approximately 1 g/cm³. Since the object's density is less than that of water, it will displace enough water to support its weight, allowing it to float. This principle is based on Archimedes' principle of buoyancy.
