I worked out the volume by doing the area of the square x the depth = 0.00025
And I don't know what to do next. Thank you
Since this has been diluted, you next need to find what this would be in the original sample. So if you have 7 cells/0.00025mm^3 in a sample that has been diluted 200 times, what would your original sample be?
This will give you your answer which you need to convert to standard form.
