volume in proportion to the number of pennies being used‚ the slope of the line equals the density of one penny. 3. The density of copper is 8.89‚ while the density of the Pre-1982 Pennies is 8.17. This means that although the penny’s density is close to that of copper‚ the penny is not all copper‚ but an alloy made up of different metals‚ but primarily of copper. 4.
