Presentation Transcript

  1. EXPLORING SOLIDS

  2. POLYHEDRONS • A solid that is bounded by polygons, called faces.

  3. How many faces, edges, and vertices?

  4. EULER’S FORMULA F + V = E + 2 F – Faces V – Vertices E – Edges

  5. 2nd day review previous slides

  6. Types of Polyhedra

  7. Prism

  8. Prism • A Prism has opposite faces that are congruent.

  9. A cubeis a prism with six square faces. Other prisms and pyramids are named for the shape of their bases.

  10. Square Pyramid

  11. A cubeis a prism with six square faces. Other prisms and pyramids are named for the shape of their bases.

  12. Timed Challenge after reviewing shapes. 2:30 • 3rd day

  13. Cone

  14. Cylinder

  15. Sphere

  16. 3rd day review previous slides and shapes. Start with concave and convex

  17. Regular Polyhedron • All visible faces are congruent.

  18. Concave or Convex?

  19. Convex Polyhedron

  20. Concave Polyhedron

  21. Surface Area of Prisms and Cylinders

  22. Height • Distance between the two bases

  23. Find Surface Area

  24. Surface Area of a Right Prism • S = 2B + Ph • S – Surfce Area • B – Base Area • P – Base Perimeter • h – Distance between bases
