SOLIDS
VISUALIZING GEOMETRIC MODELS

There are lots of interesting three-dimensional (3-D) shapes to study in mathematics.  These shapes are the fundamental shapes of many objects you find around you, both naturally and man-made.  We’ll begin by looking some 3-D shapes which can be referred to as solids.

Then we’ll take a closer look at prisms.  Prisms are named by the shape of their bases.  A rectangular prism has six faces, twelve edges, and 8 vertices.

Three-dimensional objects look differently from different views.  We’ll examine a shape built out of cubes and see how differently it looks from a top view, side view, and back view. We will use isometric dot paper to sketch 3-D objects.
