A cone has 1 vertex and 1 edge. How many surfaces does it have?

Show answer

2

A cone has one vertex, one edge, and two surfaces: one curved surface and one plane circular surface. So it has 2 surfaces.

A cube has 6 faces. If each face is a square and all six faces are congruent, what is the main shape family of the cube?

Show answer

Polyhedron

A cube has flat polygonal faces, straight edges, and sharp corners. That makes it a polyhedron.

A cuboid has 8 vertices and 6 faces. Using Euler's formula, how many edges does it have?

Show answer

12

Euler's formula is V + F - E = 2. Substitute V = 8 and F = 6: 8 + 6 - E = 2. So 14 - E = 2, hence E = 12.
