Chapter 8: Measurement

Flying Dogs

INTRODUCTION

Dogs are allowed on airplanes, but only in crates. If you want to take your dog with you on a trip, you have to find the right crate.

 

THE TASK

You must choose an appropriate sized crate so that your dog can go on a plane.

 

THE PROCESS

You will sharpen your skills as an architect by practising on the following websites. You boss does not want you practising on her house. She wants you to be a fully trained architect first!

  1. Go to the Dog Breed Size Chart. Decide the breed of dog you are going to take on your trip.

  2. Record the size of your dog.

  3. A crate for a dog should be comfortable. It must be large enough that the dog can stand and turn around easily. How large should a crate for your dog be? Record the height, length, and width of crate you need.
  4. Estimate whether the volume of the crate will be greater than or less than 1 m3? Explain.

  5. Calculate the area and perimeter of the floor of the crate using the length and width from your floor plan.
