Suppose you have a book on the counter and you decide to estimate the thickness of each sheet. You take ruler that is graduated into millimeters and determine the length from the front cover to the back cover is 2.6 cm. Furthermore, you look down at the last page and conclude the book has 348 pages. How thick do you predict each sheet of the book is? Jargon Alert: The number of "sheets" is the number of "leaves" or physical pieces of paper that are bound to make the book. Remember that each sheet or each piece of paper has both a front side and a backside. Each side is a unique page. This means that each "sheet" consists of two pages. For this problem assume the front cover and the back cover are equal in thickness to the sheet thicknesses in between. Give your answer in units of centimeters, however DO NOT include the letters "cm" in your answer. Only include the numerical portion in the answer box, else the answer (even if correct) will be counted as incorrect. Keep three decimal places in your answer.
