#### Working with Shapes in Three Dimensions

**INTRODUCTION**

Geometric figures on a flat surface, such as circles, triangles, squares, and rectangles have two dimensions. For example, a rectangle has length and width. Items that are solid like building blocks and rectangular erasers or hold something such as game box, or crayons have a third dimension called height. Height is also called depth or thickness.

There are many three-dimensional shapes hat occupy space and have surface area. The amount of space a three-dimensional (or solid) shape occupies is called volume. Volume also refers to how much a container can hold. Another word for the amount that a container can hold is also called its capacity.
