Chapter 1: Introduction to the Engineering Profession
1.20 Estimate the amount of copy or printing paper that you use every year. A 500-sheet ream
of copy paper has an approximate mass of 5 pounds (2.27 kg). How much of this
consumption is truly necessary, and how much of your own paper consumption could be
avoided? State your assumptions.
SOLUTION
For example, on average, I use 15 pages per day; then on a yearly basis, I use 5475 pages
N
(15 x 365).
5475 pages 5 pounds pounds of paper
