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 for a person with your dimensions.
