Can someone please explain how to do this (Physics)?

How does the force of friction depend on the amount of surface area in contact between 2 surfaces (weights and a sled)? Explain.

Thanks for any help.

    t doesn't

    the force of friction between two surfaces depends only on the force pressing the two surfaces together (called the normal force) and the nature of the two surfaces in contact (represented by the coefficient of friction)

    if you put a book on a table, and assuming the book is made of the same material on all sides, whether you put the book on its side or face down will not effect the frictional force
