Question

Assume that an average cell has a diameter of 6 micrometers (6x10^6 meter), which means it has a volume of 100 cubic n 10^10 cells per cm. Estimate the number of cells in a​ liter, using the fact that a cubic centimeter equals a milliliter.

Answer 1

8.84*10^{12} cells in a liter

Explanation:

If a cell has a diameter of 6*10⁻⁶ m, then its volume is:

`V_(cell)=(4\pi)/(3)((d)/(2))^3\ m^3=1.13*10^(-16)\ m^3= 1.13*10^(-10)\ cm^3`

If there are 1000 cubic centimeter in a liter, then we can obtain the amount of cells dividing the total volumen and the volume is takes every cell:
