3. Space Figures
A space figure is a 3-dimensional figure. We commonly think of cubes, prisms, and spheres and cylinders.
Rectangular prism
Triangular prism

4. Space figures
Cylinder
Square prism (cube)

5. Space figures
To name a space figure, we first look at the shape of the base. There are two of them.
If the base is a square, the space figure is a square prism.
If the base is a triangle, the space figure is a triangular prism,
If the base is a circle, the space is a cylinder.

6. Try This
Name the following space figures:

7. Try This

11. Try This
Name the figure:
Trapezoidal prism

12. Space Figures and Nets
If you could take a space figure such as a square prism, and take it apart so that is lies flat, you would have a shape called a net
For example:
This is a square prism. . .

13. Nets
And here is one way to draw the net:

14. Nets
Here is a triangular prism:

15. Nets Here is a triangular prism: And below is the net:
Notice the triangles are the bases

16. Try This
Draw the net for this figure:

17. Try This
The blue rectangles are the bases.

18. Try This
Draw the net for this cylinder:

19. Try This Draw the net for this cylinder:
It is important to see that a cylinder is 2 circles and a rectangle.
