# Scale Drawings and Scale Models

We encounter scale drawings almost everyday. Maps are a good example of scale drawings as they are two-dimensional drawings that use a scale to represent an object as smaller or larger than the actual object. Most of us encounter scale drawings in a variety of places, whether it is on our phones trying to figure out how to get someplace new, or a diagram in a science book of the minuscule parts of a cell. It's important to understand how to properly utilize a scale to determine the actual size of an object or the distance between two points. While an inch might not seem very far, if the scale is 10 miles = 1 inch, you might think differently.

The same goes for scale models. Sometimes it's just not possible to create a life-size model of something, whether it is a volcano or something tiny like the nucleus of a cell. This is where making a model to scale becomes useful. Professor Burger shows you how to use ratios to find unknown scales and find unknown dimensions based on a scale. He even demonstrates real world applications of these concepts in today's free 8th Grade Math video on Scale Drawings and Scale Models.
