SOLUTION: The average number of red blood cells in 1mm(cube) of human blood is about 4500000. In order to perform a blood test, a lab tech dilute one part blood with 300 part salin solution.

Question 40301: The average number of red blood cells in 1mm(cube) of human blood is about 4500000. In order to perform a blood test, a lab tech dilute one part blood with 300 part salin solution. How many red bleed cells would you expect to find in 0.25mm(cube) of the solution?

Well if 1 cubic mm of blood has 4,500,000 cells, then .25 cubic mm would have 1/4 of that or 1,125,000 cells. Now if that solution is diluted 1:300, you would expect 1/300 of the normal number of cells in the saline solution, thus...
(1/300)(1,125,000) =
3750 cells
