The last page of a book is numbered 764. The book (not including the cover) is 3.0 cm thick. What is the average thickness of a sheet of paper in the book, in centimeters?
Hello and thank you for posting your question to Brainmass.
When converting units, we multiply our original unit with 1s as many as necessary.
However, since we have equivalence between units (such as 1m=100cm), we can write "1" in many ways as ratio of units (for example 1m/100cm = 1 or ...
This solution is provided in 263 words. It discusses how to convert units and uses simple equations and step-by-step solutions to find mass and thickness.
