Full Answer

Three-dimensional objects can either have flat faces or curved surfaces. A "prism" is a solid plane figure with four lateral faces on the sides and two parallel faces called "bases" at the top and bottom. A "cube" contains six identical square faces, while a "dodecahedron" has 12 pentagonal faces that are all equal in size and shape. An "octahedron" has eight triangular faces, while an "icosahedron" contains 20 triangular faces. A "cylinder," meanwhile, has two circular faces.
