The mass of platinum cone is more than the mass of the gold cylinder which is 7529.76 grams.
It is defined as the ratio of mass and volume. The density gives an idea of how dense the object is, and it is denoted by the symbol ρ. The unit of the density is kilogram per cubic meter.
The volume for the cylinder = π(6/2)²(5) = 141.37 cubic cm
The density for gold = 19.3 gram/cm³
Mass of gold cylinder = 19.3×141.37 = 2728.44 grams
The volume of the cone = (π(8/2)²×21)/3 = 351.85 cubic cm
The density for platinum = 21.4 gram/cm³
Mass of platinum cone = 21.4×351.85 = 7529.76 grams
Thus, the mass of platinum cone is more than the mass of the gold cylinder which is 7529.76 grams.
