Question

Solve the following problem:A red blood cell has a diameter of 7.5 um (micrometers). how many red blood cells would be able to form a line 0.75 feet long? (Answer must be in significant figure format)

Answer 1

Explanation:

The diameter of the red blood cell = 7.5 μm

The diameter of the redblood cell = 7.5 x 10⁻⁶m

The length of the line = 0.75 feet

1 foot = 0.3048m

0.75 feet = 0.3048 x 0.75

0.75 f
