SUMMARY
The discussion focuses on determining the mass density of a solid object that floats in ethyl alcohol, which has a known density of 806 kg/m³. The object is 68.2% submerged, leading to the conclusion that the density of the object can be calculated using the formula p(object) = p(alcohol) * 0.682. This relationship is derived from the equilibrium condition of buoyancy, where the upward thrust equals the weight of the object. The user expresses confusion due to the lack of similar examples in their textbook.
