Three-Dimensional Shapes

2. Three-dimensional Shapes (3D)
These shapes are solid or hollow.
They have three dimensions – length, width and height.

3. Face Part of a shape that is flat.(Or curved) E.g. A cube has 6
of these.

4. Edge
The line where two faces meet.
E.g. A cube has 12 of these.

5. Vertex (Vertices) The place where three or more edges meet.
This pyramid has 4 of these.

6. Cube
A three- dimensional shape which has 6 square faces all the same size.
Some faces parallel
Some edges parallel
Some faces perpendicular
Some edges perpendicular

7. Face of a cube

8. 2 3 1 5 6 4

10. Rectangular Prism
A three- dimensional shape which has 6 rectangular faces.
Some faces parallel
Some edges parallel
Some faces perpendicular
Some edges perpendicular

11. Faces of a rectangular prism

12. 3 1 2 2 4 1

14. Cone
A three dimensional shape with a circle at its base and a pointed vertex.
No parallel faces or edges
No perpendicular faces or edges

15. Face of a cone

16. 1

18. Cylinder A three- dimensional shape with circular ends of equal size.
Some faces parallel
Some edges parallel
Some faces perpendicular
No edges perpendicular

19. Face of a cylinder

20. 1 1 2

22. Pyramid
A three-dimensional shape which has a polygon for its base and triangular faces which meet at one vertex.
E.g. Triangular pyramid
Square pyramid
Hexagonal pyramid
Pentagonal pyramid

23. Face of a pyramid

24. Square base pyramid No faces parallel Some edges parallel
No faces perpendicular
Some edges perpendicular

25. 1 2 1 4 3

27. Sphere
A perfectly round three-dimensional shape, like a ball. It has only one curved face.
No parallel faces or edges
No perpendicular faces or edges

36. Creating 3- Dimensional Shapes
Cut out the shape along the outer edge.
Fold all the edges of the shape first.
Use a small amount of glue on the shaded areas.
Carefully fold and press the shaded areas to the back of the faces.
