    Does the room have to be a square? If so calculate the dimensions of the square. If you know the width of the room and the total width of each shelf/corridor then you know how many shelves/corridors can fit into the room. That's a good start at least. Where you gettin tripped up?

    I'm not sure how big the shelves are though.
