2. REVIEW - a three-dimensional figure encloses a part of space

3. Three-Dimensional Figures
faces – the flat surfaces
edges – the segments formed by intersecting faces
vertices – the points formed by intersecting edges

4. faces
edges

5. A three-dimensional figure encloses a part of space.
prism – has two parallel and congruent bases in the shape of polygons; the shape of the bases tells the name of the prism

6. A three-dimensional figure encloses a part of space.
pyramid – has a polygon for a base and triangles for sides; the shape of the base tells the name of the pyramid

7. A three-dimensional figure encloses a part of space.
cone – has curved surfaces, a circular base and one vertex

8. A three-dimensional figure encloses a part of space.
cylinder – has curved surfaces, two circular bases and no vertices

9. A three-dimensional figure encloses a part of space.
sphere – has no faces, bases, edges, or vertices; all the points are the same distance from a given point called the center

10. volume – the amount of space inside a three-dimensional figure
The volume (V) of a rectangular prism equals the product of its length (l), its width (w), and its height (h).
V = lwh h w l

11. volume – the amount of space inside a three-dimensional figure
The volume (V) of a cube equals the product of three of its sides (s).
V = s3 s s s
