**Three-Dimensional Figures**• faces – the flat surfaces • edges – the segments formed by intersecting faces • vertices – the points formed by intersecting edges**faces**edges vertices**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**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**A three-dimensional figure encloses a part of space.**• cone – has curved surfaces, a circular base and one vertex**A three-dimensional figure encloses a part of space.**• cylinder – has curved surfaces, two circular bases and no vertices**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**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).
