What is the volume of a generalized Klein bottle, say using characterizing dimensions such as greatest length l, width w, intersection area a?
I've never heard of a Klein Bottle before.
There're weird! Sort of a 3 dimensional version of a mobius strip?
There are instructuions in this wikipaedia page on how to make one! Does someone want to give it a go?
You could upload a photo of your creation to show us!
