The lower half of Mr. Andersen's head explains why cells are small. This video begins with a simple geometry problem and ends with a discussion of Allen's Rule and reasoning for the microscopic nature of cells.

I think you mean the opposite thing. You mean big surface area and small volume, right? You might want to correct that. Anyways a helpful video, as usual!
that's a cool way to compare volumes
great demo!!!

I liked the demonstration in the beginning which helped tie the concept neatly in my brain. Great stuff, thanks!
