If 1500 white blood cells are lined up side by side they would form a row 1.0 inch long what is the average diameter in micrometers of a single white blood cell? (1 inch=2.54 cm)

First, we note that the 1500 white blood cells would form a row that is 2.54 cm long and figure out how many micrometers that is. 1 cm = 10,000 micrometers so 2.54 cm = 25,400 micrometers. Next we divide that by the 1500 white blood cells to find out how long each one is. 25,400/1,500 = 16.93 micrometers each. That is the length, or diameter, of each white blood cell.

The answer is bhope this

Just took the quiz on edgenuity and the correct answer is "c.  4.54 x  10–12  j"
