So, the first shelf requires (1.90 kg x 22.0 cm) = 41.8 J of work. The second shelf requires (1.90 kg x 33.0 cm) = 62.7 J of work. The third shelf requires (1.90 kg x 66.0 cm) = 125.4 J of work. The fourth shelf requires (1.90 kg x 99.0 cm) = 188.1 J of work. The fifth shelf requires (1.90 kg x 132.0 cm) = 250.8 J of work. In summary, the total work required to fill the bookshelf is 668.8 J.

In a certain library the first shelf is 12.0 cm off the ground, the remaining 4 shelves are each spaced 33.0 cm above the previous one. If the average book has a mass of 1.90 kg with a height of 22.0 cm, and average shelf holds 29 books (standing vertically), how much work is required to fill this book shelf from scratch, assuming the books are all laying flat on the floor to start?

"Very hard"?

You consider multiplying integers "very hard"?

The work to put each book on a shelf is the weight of the book times the height it is lifted to the shelf.
