# A stack of eight compact disks is 1.0 centimeter high. What is the thickness of one compact disk (CD) in centimeters? What is the thickness of one CD in millimeters?

(2) Answers

(physics: really?) It's 0.125 cm or 1.25 mm. Divide 1cm (or 10mm) by 8.

One CD is 0.125 because 1.0 divided by 8 is 0.125 Millimetres of 1 CD would be 12.5 millimetres.
