Here's why:
* Different Editions: Roald Dahl's books have been published in numerous editions over the years, each with varying sizes, paper quality, and binding.
* Number of Books: The "Roald Dahl collection" could refer to a single volume compilation, a set of his most popular titles, or a complete collection of all his works.
* Weight Varies: Even within a single edition, the weight will fluctuate based on the number of pages, the type of paper used, and the size of the book.
If you want to know the weight of a specific edition:
1. Identify the edition: Specify the publisher, year of publication, and the number of books in the collection.
2. Check online retailers: Websites like Amazon or Barnes & Noble often list the weight of individual books or sets.
I hope this helps!
