Estimate the fraction of the total volume in this cube that is extracellular matrix? How many eukaryotic cells can fit in this 10^6 mum^3 cube? Assume the average volume of a cell is 10^3 mu m^3. How many eukaryotic cells can fit in this 10^3 mu n^3 cube? Assume the average volume of a cell is 10^3 mu m^3. How many prokaryotic cells can in this 10^3 mu m^3 cube? Assume the average volume of a cell is 1 mu m^3

Solution

Answer 3. Let\'s assume each cell has volume = 10³ um³ and there are 1000 such cells in the cube. So, the volume occupied by all the cells = 1000 X 10³, i.e. = 10⁶ um³

The volume of cube itself is 10⁶ um^3, So, there is no space left for the extracellular matrix in the cube.

Answer 4. As mentioned above, The volume of cube is 10⁶ um³, If each cell has volume of 10³ um³, lets assume x number of cells can be accomodated in the cube, then

10³ * x = 10⁶

or, x = 10⁶/10³

x = 1000 cells

Answer 5. Only one cell of volume 10³ um³ can be accomodated by the cube having volume of 10³ um^3.

Answer 6. 1000 cells of volume 1 um³ can fit in the cube of 10³ um³, as can be calculated the same way in the answer 4.
