- The distance from a 6 cm high object to a screen is 80 cm. Where should a lens with a 15 cm focal length be set up so that it creates a sharp (enlarged or reduced) image of an object on the screen? How big are the pictures in both cases?

Unfortunately, there's no formula i know about, so i have no idea how to solve this...
