Some research has shown approximately 21,000 germs per square inch can live on a desktop, so if the typical classroom desktop is 144 square inches, that would be approximately 3,024,000 germs on each desktop. Usually, the teacher's desk is at least twice that size, so the teacher's desk could hold 48,384,000 germs. Each keyboard can hold about as many germs as a desktop. As you can see, the typical classroom could easily harbor well over 100 million germs.
