  1. Some Geometrical Objects in Our Environment

  2. Solid Figures Solid Figures Some objects which we can see in our environment are called solid figures. You have probably seen objects that have these shapes. Some objects which we can see in our environment are called solid figures. You have probably seen objects that have these shapes. rectangular prism sphere cube cylinder cone pyramid You can think of real objects that have these shapes. For example, a tennis ball is a sphere. You can think of real objects that have these shapes. For example, a tennis ball is a sphere.

  3. - This box is a rectangular prism. - Each corner of the box is a vertex of the prism. - Each edge of the box is an edge of the prism. - Each side of the box is a face of the prism. Rectangular prism Rectangular prism - This box is arectangular prism. - Each corner of the box is avertexof the prism. - Each edge of the box is anedgeof the prism. - Each side of the box is a face of the prism.

  4. 1. Rectangular prism Vertex Edge Face A rectangular prism has 8 vertices, 12 edges and 6 faces. A rectangular prism has 8 vertices, 12 edges and 6 faces. 2. Cube Vertex Edge Face A cube has 8 vertices, 12 edges and 6 faces. A cube has 8 vertices, 12 edges and 6 faces.

  5. 3.Sphere A sphere has no faces, edges or vertices. 4. Cylinder Face Edge A cylinder has 0 edges and 2 faces.

  6. 5.Cone Vertex Edge Face A cone has 1 faces, 1 vertex and 0 edge. 6. Pyramid Vertex Face Edge A pyramid has 5 faces, 5 vertices and 8 edges. A pyramid has 5 faces, 5 vertices and 8 edges.
