120mm = 0.00012km
A magnification of 40 times is needed to achieve a 120mm image of a 3mm object. This is calculated by dividing the desired image size (120mm) by the original object size (3mm). So, a magnification factor of 40x would enlarge the 3mm object to 120mm.
80mm x 120mm equates to 3.15 inches x 4.72 inches.
