# Thread: mapping the surface area

1. ## mapping the surface area

How can I map the surface area onto 2 dimensions:
A 4-sided pyramid, but without the base. Assume that the base is units b wide and b long. And the pyramid is of height h.

4. Do you mean a function that when graphed looks like a pyramid?

Like
which when graphed will give an inverted cone, but for a pyramid?

Yeah, Thanks

6. Hmm, ok.....now the hard part. I'm not sure what it would be for a pyramid. Sharp edges always make it hard. I'll think about it and post again if I can come up with anything.
