How long and wide is the sacred stone in Monkey King?

The golden hoop weighs 13500 Jin, is 20 feet long, and the bowl mouth is thick. If it is changed to the international system of units, the volume of this stick is about 0.2 cubic meters and the mass is about 6750 kilograms. Its density is about: ρ = m/v = 6750kg ÷ 0.2m3 = 33750kg/m3 = 33.75g/cm3. That is to say, theoretically, the density of the golden hoop is much higher than that of osmium (ρ osmium =22.8g/cm3), the densest substance on the earth. Specifically, the golden hoop belongs to. 22.8g/cm3 is normal, indicating that the golden hoop may exist, but it may not be an earth object.
