Question

The brain weighs roughly 1 kg and contains 10^12 cells. Calculate the average volume of a brain cell assuming that each cell is filled entirely with water and 1 cubic centimeter of water weighs 1 g. What is the diameter of the average nerve assuming a perfect sphere?

Answer 1

Answer:

$1x10^{-9}$ cubic centimeters is the volume of the cell

Explanation:

In order to calculate that we just have to divide a thousand grams which is the amount of grams that there are in a kilogram, by the number of cells that there are in the whole brain:

$Volume of the cell:\frac{volume}{amount of cells}\\ Volume= \frac{1000}{1x10^{12} } \\Volume:x10^{-9}$

So as we know a gram equals one cubic centimeter, so we know that each brain cell has a volume of $1x10^{-9}$ cubic centimeters.
