Solid Shapes |

Solid Shapes.
Objects that occupy space are called solid shapes.
Their surfaces are called faces. Faces meet at edges and edges meet at vertices.
Some examples of solid shapes: Cone, Cuboid, Sphere, Cylinder, Cube.
Cube has 6 faces which are equal squares, 12 equal edges and 8 vertices.
Cuboid has 6 rectangular faces where opposite faces are equal. It has 12 edges and 8 vertices.
Cylinder has three faces. Two of them are flat while the third one is curved.
Cone has 2 faces. One of them is flat and circular while the other is curved.
Cone has one circular edge and one vertex.
Sphere has neither any edges nor vertices. It has only one curved surface.
