We usually think of pies as circles. But these fine folks baked a "pie-cosahedron" -- that is, an icosahedron, or 20-sided shape, made of pie! They cut and bent their own triangle-shaped metal pie tins. Then they made pecan pie, changing the recipe to be less gooey so pies wouldn't fall apart. After baking the 20 triangle pies, they used magnets to hold all the tins in this shape. The question is, how many people does this geo-dessert feed?
