Diana is moving into a new apartment. She wants to get a heavy chair up to her second-floor apartment, but it will only fit through the window.

Diana could strap the chair to her back and climb a ladder straight up to her window.

Or Diane could use a simple machine, by sliding the chair up an inclined plane to get to the window. Which of the following is a disadvantage of using an inclined plane to move the chair, instead of climbing a ladder to get to the window?
