what if i told you there exists a shape with infinite surface area but a finite volume...

wacky right??

the shape is called Gabriel's horn and is formed by taking the graph of 1/x for the domain x≥1 and rotating it in 3 dimensions around the x axis to get a shape like (surprise surprise) Gabriel's horn!!

as a result you get a shape which if you filled with paint, would never be able to fully paint the outside with.

don’t believe me? i wouldn’t either so here’s the link to the wikipedia
