If by "regular sized" copies you mean the copy is the same size as the original,
the distance from the lens to the receiving belt should be the same as the distance
from the object to the lens. The formula is: hi/ho = di/do, where hi and ho are the
height of the image and object respectively, and di and do are the distance of the
image and object from the lens. So for an image the same size as the object, its
distance from the lens should be the same as the distance to the object.
The correct answer choice is 30 cm - same as the distance of the original.
