Taking your surf board to Hawaii could be a little tricky, but some airlines actually allow it! If you designed a product for sale as part of your Unit 1 Project, you should know there are restrictions on the size of parcel you can mail, just as there are restrictions on airline luggage.

 

The air traveller in the photograph will be checking more than two bags prior to his flight. Airlines in Canada have restrictions on the number and weight of bags travellers can check. Airlines also limit the linear dimensions of each checked bag. The total of the length, width, and height cannot exceed 158 cm. You will be assessed a surcharge if you exceed the limits for the number, weight, or linear dimensions of checked baggage.

 

Surcharges for extra pieces, or for overweight and oversized items, can be pricey. Baggage restrictions are just one type of linear measurement problem you will encounter in this lesson.

 

Lesson Questions

 

In this lesson you will explore these questions:

  • How do you solve perimeter, circumference, and size problems based on linear dimensions?
