Final answer:
The volume of an entire grid on a Neubauer hemocytometer can be calculated by multiplying the area of a square within the grid by the height of the coverslip. This gives a volume of 0.008 mm³ or 0.000008 mL.
Step-by-step explanation:
The volume of an entire grid on a Neubauer hemocytometer can be calculated using the known area of each square within the grid. The grid is used to count cells in a measured volume of a sample. In Figure 9.8b, it is stated that the area of each square is 0.04 mm². Additionally, it is mentioned that the coverslip is 0.2 mm above the grid. To find the volume, you can multiply the area of a square (0.04 mm²) by the height (0.2 mm). This gives a volume of 0.008 mm³ or 0.000008 mL
