**anatomy & physiology question** if you are at a 60X magnification and the field diameter is 3.2mm an object that's about 1/4th the size of the field diameter what is the size of the object?

0.8mm.

Explanation:

If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.
