The diameter of a white blood cell under magnification appears to be 0.3 centimeters. What is the diameter of the white blood cell in millimeters?

30 millimeters

there are 10 millimeters in a centimeter

To find the diameter of the white blood cell in millimeters, we need to convert centimeters to millimeters.

The conversion factor between centimeters and millimeters is 10. This means that there are 10 millimeters in 1 centimeter.

Given that the diameter of the white blood cell appears to be 0.3 centimeters, we can now convert it to millimeters by multiplying 0.3 by 10:

0.3 centimeters * 10 = 3 millimeters

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