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.

8.84*10^{12} cells in a liter

Step-by-step explanation:

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

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:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
