  • 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.

  • Cube has 6 faces which are equal squares,12 equal edges and 8 vertices.

  • 6 faces.

  • Equal squares.

  • 12 equal edges.

  • 8 vertices.

  • Cuboid.

  • Cuboid has 6 rectangular faces where opposite faces are equal. It has 12 edges and 8 vertices.

  • 6 rectangular faces.

  • Opposite faces are equal.

  • 12 edges.

  • 8 vertices.

  • Cylinder.

  • Cylinder has three faces. Two of them are flat while the third one is curved.

  • 3 faces.

  • Flat.

  • Curved.

  • The flat surfaces are circles having same size.

  • The flat surfaces meet the curved surface at the circular edges.

  • Circular edges.

  • Cone.

  • Cone has 2 faces.

  • One of them is flat and circular while the other is curved.

  • Flat and circular.

  • Curved.

  • Cone has one circular edge and one vertex.

  • Circular edge.

  • Vertex

  • Sphere.

  • Sphere has neither any edges nor vertices. It has only one curved surface.

  • Curved surface.
