Tabulate the annual world production (metric tons/year) and the densities (kg/m3 ) of carbon steel, PE, softwood, and concrete. You will find the data for these materials in Chapter 15. Use an average of the ranges given in the data sheets. Calculate, for each, the annual world production measured in m3 /year. How does the ranking change?
