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

`1x10^(-9)` cubic centimeters is the volume of the cell

Step-by-step 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:(volume)/(amount of cells)\\ Volume= (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.
