K and L mark the diameter of a collecting duct. Draw a straight line connecting K and L on the collecting duct in the photomicrograph, measure that line, and write down the measurement. The true distance between K and L is $0.06\text{ mm}$. Determine the magnification of the photomicrograph and give it to the nearest whole number.
