The average number of pages in a book is around 2 0 0 pages . Therefore , the total number of pages in all the books ever written would be : \n \n 1 7 0 million books x 2 0 0 pages per book = 3 4 billion pages \n \n It ' s important to note that this is just an estimate and the actual number of pages in all the books ever written could be higher or lower .
