Answer 2

The diameter of the white blood cell in millimeters is 3 mm.

Explanation:

Given : The diameter of a white blood cell under magnification appears to be 0.3 centimeters.

To find : What is the diameter of the white blood cell in millimeters?

Solution :

The diameter of a white blood cell is 0.3 centimeter.

Conversion of centimeter into millimeters,

`1\ cm=10\ mm`

So, 0.3 cm into mm is

`0.3\ cm=10* 0.3\ mm`

`0.3\ cm=10* (3)/(10)\ mm`

`0.3\ cm=3\ mm`

Therefore, the diameter of the white blood cell in millimeters is 3 mm.
