1. The problem statement, all variables and given/known data How far apart are an object and an image formed by a 72.4 cm focal length converging lens if the image is 2.54x larger than the object and is real? (in cm) 2. Relevant equations m=-(di/do) m=f/(f-do) (1/di)+(1/do)=(1/f) 3. The attempt at a solution I've tried manipulating these equations to find the distance, but either I don't come up with a reasonable value or I end up with too many variables.
