Styrofoam was almost completely out of the water while floating while ice was almost completely under water while floating. 3.) The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume.The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Measure the volume of an object by observing the amount of fluid it displaces. u would have to measure something in milliliters and then fill it with water and then drop the styrofoam into it to measure the volume.
