Question

an adult person has roughly 24 into 10 power 12 red blood cells the average diameter of each blood cell is 8 into 10 power 9 km if the cells are present then how long would a line be​

Answer 1

Given:

Number of red blood cells in an adult person

$= 24 \times {10}^{12}$

Average diameter of each cell

$8 \times {10}^{9}$

To find:

The length of the line if the red blood cells are placed in a line.

Solution:

If the red blood cells are placed in a line then the length would be equal to the sum of the diameters of all the red blood cells, which means the length will be the product of average diameter and number of cells.

Length of the line

$24 \times 8 \times {10}^{12} \times {10}^{9} km$

$= 192 \times {10}^{12 + 9} km$

$= 192 \times {10}^{21} km$

Therefore the length of the line will be

$192 \times {10}^{21} km$
