3. A solution containing 0.001 g/ml Fe2O3 is diluted 10,000 times. Ultramicroscopic counting in a dilute solution yielded an average of 3 particles per field of view with a diameter of 0.04 mm and a depth of 0.04 mm. Assuming that the particles are spheroidal and that their density is 5.2 g/cm3, find what the diameter of the particles is.
