You are observing a slide of green cells under the 4X objective. Each cell covers roughly 1/8th of the width of your field of view. How large of a diameter do these cells have?

The equation I found is:

Size of cell= field diameter/ # of cells that fit across field

So the objective is 4X then the field diameter is 4,500 micrometer... but I can't figure out the number of cells that fit across the field...Is it impossible to estimate this?
