* Size: A tome is usually a large, thick book.
* Material: The materials used for the cover and pages affect its weight. Leather, metal, or wood covers add weight, as do thick, high-quality paper.
* Content: The number of pages and the density of the text will impact the tome's weight.
Think of these examples:
* A small, paperback tome: Might be around 1-2 pounds
* A large, hardcover tome: Could weigh 5-10 pounds or more
* An ancient, bound-in-leather tome: Potentially 20-30 pounds or even heavier
So, to figure out how heavy a specific tome is, you'd need more information about it.
