Unit+1.+Area,+Volume+&+Scaling

Objectives.
The main goal of this unit is for you to have a working definition of the terms **linear dimension, area** and **volume,** be able to estimate the area of any shape, and know how each of these changes as the object's size changes.
 * I can give a working definition of the term **area**.
 * I can estimate the area of an arbitrary shape.
 * I can determine the **factor** by which the area of a shape changes when its **linear dimensions** are changed by a given factor, and //vice versa//.
 * I can give a working definition of the term **volume.**
 * I can determine the factor by which the volume of a shape changes when its linear dimensions are changed by a given factor, and //vice versa//.
