As shown in the above figure, a solid object has a density of 1200 kg/m3 and a volume of 8.00x10^-5 m³. It is lowered on a string into water and completely submerged without touching the container. The density of water is 1000 kg/m3. Keep 3 decimal places in all answers. (Don't use scientific notations.) Without the string, would the solid object sink in water or float in water? No submission.
