A travel book has 72 two sided pages each of which is 140 inch thick where each two sided page is perceted by a protective 160 inch thick piece of paper and each side of the book is bound by a 16 cove?

Answer 1

To calculate the total thickness of the travel book, we need to consider the thickness of the pages, the protective paper, and the covers. Each of the 72 pages is 0.140 inches thick, totaling 10.08 inches for all pages (72 pages x 0.140 inches). The protective papers add another 11.52 inches (72 pages x 0.160 inches). Finally, the two covers contribute an additional 0.32 inches (16 inches x 2 covers). Adding these together, the total thickness of the book is approximately 21.92 inches.
