The width of a human hair is about 17 micrometers. how many human erythrocytes could fit across the width of a hair? how many ecoli bacteria could fit?

Two erythrocytes and 34 E.Coli Bacteria

Explanation:

Given -

Size of human hair i.e width of human hair is equal to micrometers

Size of an average erythrocytes or red blood cell is equal to 8 micrometers in diameter.

So the number of human erythrocytes could fit across the width of a hair is equal to

Substituting the given values, we get -

Width of E.Coli bacteria is equal to micrometer

Number of E.Coli bacteria that could fit in with in the human hair is equal to
