This object has 6 sides and counts from 1 to 60 from top to bottom. The prime numbers are cut all the way through the wall so they stand out. Upon inspection, one will notice that the 1 column and the 5 column have all of the prime numbers after 3. Why is that?
Hopefully this is useful for teachers, students and math enthusiasts. It is also a useful bucket for knickknacks, pens, pencils, tools, and other junk on my desk. (prime junk).
