Lesson 5

Lesson 5: Scaling, Volume, and Capacity

 

Focus

 

Renting a truck to move your belongings can be tricky! If the truck is too big, you will have wasted money and fuel, and the extra room might allow your furniture and boxes to move around too much as you drive. If the truck is too small, you will waste time and fuel making multiple trips.

 

Many rental moving trucks are referred to by their lengths—a 14-ft, 17-ft, or 24-ft truck. In most cases, the height and width of these trucks are the same: only their lengths are different. How does this change in length affect the capacity of each truck?

 

Throughout Lesson 5 you will look at how volume and capacity are affected by changes in linear measurements.

 

Lesson Question

 

In this lesson you will investigate the following question:

• How does altering an object’s linear dimensions affect the object’s volume and capacity?
