  1. 3-Dimensional Solids Return to table of contents

  2. The following link will take you to a site with interactive 3-D figures and nets.

  3. Polyhedron A 3-D figure whose faces are all polygons Sort the figures into the appropriate side. Polyhedron Not Polyhedron

  4. 3-Dimensional Solids Categories & Characteristics of 3-D Solids: • Prisms • Have 2 congruent, polygon bases which are parallel • to one another • 2. Sides are rectangular (parallelograms) • 3. Named by the shape of their base click to reveal Pyramids 1. Have 1 polygon base with a vertex opposite it 2. Sides are triangular 3. Named by the shape of their base click to reveal

  5. 3-Dimensional Solids Categories & Characteristics of 3-D Solids: • Cylinders • Have 2 congruent, circular bases which are parallel • to one another • 2. Sides are curved click to reveal Cones 1. Have 1 circular bases with a vertex opposite it 2. Sides are curved click to reveal

  6. 3-Dimensional Solids Vocabulary Words for 3-D Solids: Polyhedron A 3-D figure whose faces are all polygons (Prisms & Pyramids) Face Flat surface of a Polyhedron Edge Line segment formed where 2 faces meet Vertex (Vertices) Point where 3 or more faces/edges meet

  7. Sort the figures. If you are incorrect, the figure will be sent back.

  8. 1 Name the figure. A Rectangular Prism Triangular Pyramid B C Hexagonal Prism D Rectangular Pyramid E Cylinder F Cone

  9. 2 Name the figure A Rectangular Pyramid B Triangular Prism C Octagonal Prism D Circular Pyramid E Cylinder F Cone

  10. 3 Name the figure A Rectangular Pyramid B Triangular Pyramid C Triangular Prism D Hexagonal Pyramid E Cylinder F Cone

  11. 4 Name the figure A Rectangular Prism B Triangular Prism C Square Prism D Rectangular Pyramid E Cylinder F Cone

  12. 5 Name the figure A Rectangular Prism B Triangular Pyramid C Circular Prism D Circular Pyramid E Cylinder F Cone

  13. For each figure, find the number of faces, vertices and edges. Can you figure out a relationship between the number of faces, vertices and edges of 3-Dimensional Figures?

  14. Euler's Formula F + V - 2 = E The number of edges is 2 less than the sum of the faces and vertices. click to reveal

  15. 6 How many faces does a pentagonal prism have?

  16. 7 How many edges does a rectangular pyramid have?

  17. 8 How many vertices does a triangular prism have?
