The number of white blood cells present in the body of a 140-lb person is 2.646 x 10¹¹.

What are white blood cells?

White blood cells are also present in the body. They work for the immune system of the body.  

First, calculate the microliters of blood there are in a 140lb person.

140 x (2.7 x 10⁴)

140 x (2.7 x 10 x 10 x 10 x 10)

140 x 27,000

3,780,000 of microliters of blood in a 140lb person

Then, the white blood cells in a 140lb person

3,780,000 x (7 x 10⁴)

3,780,000 x (7 x 10x 10 x 10 x 10)

3,780,000 x (70,000)

264,600,000,000 white blood cells in a 140lb person

Thus, the number of white blood cells will be 2.646 x 10¹¹.
