7. 3-D SHAPES

8. We live in a three-dimensional
world. Every object you can see or
touch has three dimensions that can
be measured: length, width, and
height. The room you are sitting in
can be described by these three
dimensions. The computer monitor
has these three dimensions. Even
you can be described by these three
dimensions. In fact, the clothes you
are wearing were made specifically
