Question from Mollie, a student: Hi, my name is Mollie and I'm in 5th grade. Here's the math problem I have for homework tonight: "Larissa made a model of a polyhedron using 8 pieces of clay for the vertices and 18 straws for the edges. What type of polyhedron did Larissa make?" Thanks. |
Mollie,
I started with a hexagonal base and constructed a pyramid.
This polyhedron has 7 vertices and 12 edges. Can you see how to add one more vertex and 6 more edges?
