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?



Answer :

(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.
