Reply to comment by BrokenHS in How is density measured in porous materials? by That_Lego_Guy_Jack

Density is an absolute ratio, where the volumic mass of the water is the reference (water density =1). By dividing the volumic mass of the sponge by the water's you compare both, and will easily know if it's denser (desnity > 1) than water or not.
