Whilst the perimeter might seem pointless for a 3D shape, in order to "tick the box" of level 3 & 4 please make sure you know how to calculate the perimeter of your shape.
When working in 3D we call the perimeter the EDGE length.
The calculations can be done using algebra in the Google Sheet above, then the totals can be written up here.
Make a clear statement about which container stack has the greatest surface area, and which has the greatest volume.
Were you surprised? How did your estimates compare with your calculations?
What did you learn from the process?
How well did your team work together?
Which person do you think has the greatest area? Which person do you think has the longest perimeter? To complete this task you might have two people per person, so a group of 6. You would present it together using Google Slides and your physical measurement posters.
