i had a final exam today and one question was:
if you have a 1m wide box positioned 1 metre away from a camera and another box which is 2m wide at a distance x from the camera and both boxes have a width that appears equal in length in the snapped image, then what is the distance x?
the camera has a focal length of 1m.
i answered 2 meters. was i right?
