A red blood cell is 0.000007 m in diameter. There are about 20,000,000,000,000 red blood cells in a 125 lb person. if all the red blood cells were lined up in a line end to end how long would the line be?

Multiply 0.000007 (7x10ˆ2) by 20,000,000,000,000 (2x10ˆ13)
The answer is 140,000,000 (1.4x10ˆ8) meters
