Eight books, each 4.3 cm thick with a mass of 1.7 kg, lie flat on a table. How much work is required to stack them one on top of another?

2. Relevant equations

w= Fdcos([tex]\theta[/tex]

3. The attempt at a solution

For the first book, there is no work required. The displacement was zero therefore no work was required. For the second book, the d=4.31 since the book must be lifted up, but I am not sure how to calculate the force and figure the angle. Don't I need to know where the books are to begin with?
