Question

which of the following platonic solids is also a cone?
a. octahedron
b. hexahedron
c. none of these
d. dodecahedron
e. icosahedron
f. tetrahedron

Explanation:

Platonic solids are regular polyhedrons (octahedron, hexahedron, dodecahedron, icosahedron, tetrahedron). A cone is not a polyhedron (it has a curved surface). So none of the Platonic solids (which are polyhedrons) can be a cone.

Answer:

C. None of these
