# Packing 3D Shapes

### Why do this problem ?

This problem will allow students to engage with visualisations
of 3D shapes. By exploring the shapes present in nature, students
will begin to develop their skills of geometrical reasoning in a
concrete setting.
### Possible approach

This question could be posed individually or for group discussion.
This problem also works effectively when students are given time to
reflect on the question and look for packings in nature. Ask the
question and let students consider it over, say, a week. What
shapes and packings have they noticed in nature? Could they find
any images to share? Then consider the questions of efficient
packings. This results might make an effective display.
### Key questions

### Possible extension

Can you consider the efficiency of the various packings? (i.e.
roughly what percentage of space is taken up by the packed shapes)

Challenge Level

- Problem
- Getting Started
- Teachers' Resources

- Can you clearly describe the underlying mathematical shapes in words?
- Can you describe your method of packing the shapes clearly in words? Can you draw an effective diagram?
- How many different sensible packing methods might you try for different shapes?

Provide physical shapes for the students to manupilate.
