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?
