Pyramid Structure

A pyramid with 28 edges has 14 faces and 15 vertices.

The number of faces in a pyramid can be calculated using the formula F = E + 2 - V, where F is the number of faces, E is the number of edges, and V is the number of vertices. Plugging in the given values: F = 28 + 2 - 15 = 30 - 15 = 15.

The number of vertices in a pyramid can be calculated using the formula V = E - F + 2, where V is the number of vertices, E is the number of edges, and F is the number of faces. Plugging in the given values: V = 28 - 14 + 2 = 30 - 14 = 16
