Unfortunately, it is not possible to answer this question definitively, as the length of a book can vary greatly depending on a variety of factors. For example, the font size and type, margin size, and the content contained within the book can all contribute to the number of pages within the book. Additionally, page count can vary for a book that is printed in different formats.
In order to determine the exact number of pages within a book, you would need to know the format in which it is printed and the content contained within it. Without specific information, it is not possible to provide a definitive answer to this question.
