How many faces does an icosahedron have?

The name itself hints at the number of faces. “Icosa-” comes from Greek for twenty, and “-hedron” means face, so an icosahedron is a twenty-faced solid. That’s why the option naming the shape is the best pick here. An icosahedron has 20 faces, all of which are equilateral triangles, with 30 edges and 12 vertices. The other shapes listed have different face counts: the dodecahedron has 12 faces, the tetrahedron has 4, and the cube has 6.
