One of the most authoritative definitions of a book is related to UNESCO: A book is a type of printed work that has more than 49 pages and, like publications, is not published periodically under a fixed title.
Another definition of a book is “a set of wooden or ivory plates or a set of sheets of paper, deer skin or the like, whether handwritten or printed together, threaded or bound together.”
Another definition that seems appropriate is content produced by the author that pursues a specific goal and the book presents content around the goal axis specified by the author, and at the end of the book, the author reaches his goal and in this case, a general reference to Have no other books or articles.
Formula for obtaining the weight of each sheet of A4 paper:
Weight of one sheet of A4 paper in grams = 10000 / (paper length × A4 paper width × (A4 grams of paper
Weight of one sheet of A4 paper in grams 4.9896 = 10000 / (80 × 29.7 × 21)
With this formula, the weight of each A4 80 g paper is 4.9896 g.
500 times 4.9896 = 2.494 kg
Therefore, each 500-sheet paper package of 80 grams of A4 should weigh 2.49 kg. (Approximately 2.5 kg)
Papers are usually made of 38 grams and their weight varies according to different uses. The standard weight for copy paper is 80 grams, but in the printing industry 60 g heat is usually used. Due to the high sensitivity of copiers, it is not possible to use papers with different weights, because with a little high and low paper heat, the machine loses its proper performance, so you should always meet the standards for different paper uses. Took seriously.
“A standard paperback novel is about 6 by 9 inches. Assuming a length of 300 pages, that equates to about 15.6 ounces on average”. (Weight of 1000 books approximately based upon the size 6×9 inches = 1000× 15.6 = 15600 ounces = 442 kg answer.)
“Hardcover textbooks weigh between 2 and 7 pounds.” According to a Californian high school study, the average weight of a physics textbook is 4.8 pounds, which equals a mass of 2.18 kg.
A standard paperback with a length of 300 pages weighs about 15.6 ounces on average. It’s typically 6×9 or 5.5×8.5 inches in size, often found in bookstores, and the covers are made from paperboard with glue attaching the papers to the binding.
