How many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? Show your work. If the diameter of a grain of sand is about 2 x 10-4 meters and the diameter of a human hair is about 0.000025 meters.

Respuesta :

Diameter of grain of sand is = [tex]2*10^{-4}[/tex]

Diameter of Human hair is = 0.000025

We can write it as = [tex]2.5*10^{-5}[/tex]

So the ratio of diameter of grain of sand to diameter of human hair is 
= [tex] \frac{2*10^{-4}}{2.5*10^{-5}} [/tex] = 8

So we can say diameter of grain of sand is 8 times longer than the diameter of average cell in human body.
