problem with Saturn ring densities
This article states that the density of the A ring of Saturn is "...surface density from 35 to 40 g/cm2...". The rings of Saturn are primarily composed of chunks of rock and ice (reference: https://solarsystem.nasa.gov/planets/saturn/in-depth/#:~:text=Rings-,Rings,other%20materials%20such%20as%20dust.), with rocks being the densest common component. Even if you were to assume that a cubic cm (cm3) had no more mass than the surface density (i.e. that the density was 35-40 g/cm3), this would be the equivalent of 3.5x10^7 g/m3 or 35,000 kg/m3. Solid rock has a density of ~3,500 kg/m3 (reference: https://www.eoas.ubc.ca/ubcgif/iag/foundations/properties/density.htm), so this articles estimation would suggest that the density of Saturn's A ring is ten times more dense than solid rock, which does not seem correct given the composition.
