Suppose you determined the density of a cube to be 1.40 g/cm3. would the density of the cube be different if you had a cube made of the same material with twice as much mass? explain.

Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.
