Aside from the ones in Egypt?

How about the food pyramid? You can find it on the side of just about any almost-helathy cereal.

What are you using it for? I'm not sure if you want specific names of ancient pyramids or like the food pyramid like Alice suggested.

The other question is, are you looking for examples of pyramids in what passes for the Real World, or are you looking for three-dimensional models of pyramids, or both? (There are different kinds of pyramids, of course.)

A prism isn't a pyramid. A prism has bases that can be congruent triangles or rectangles or hexagons or whatever, and the faces between the bases are rectangular or parallelogramic - so a Droste chocolate pastilles box is a hexagonal prism. A pyramid has one base that can be a triangle or rectangle or hexagon or whatever, and the faces are triangles.

Here are a couple of incredibly cool Web sites that might help. The first one is full of the most astonishing paper models...

You could build one..... We had to build a Dodechohedron for our final "teacher math class" at UW-Madison-- I can let the secret out now (years later---well NOT THAT MANY YEARS)-- I was totally wasted when I was building mine in the hallway of my dorm drinking vodka/peach puker/OJ--- I think I got the best grade of my three "Math For Teachers" classes on that one...
