Nicola has a three dimensional puzzle made from cubes.
- There are six pieces altogether
- All six pieces are different shapes
- The pieces fit together to make a 3 by 3 by 3 cube.
Here are diagrams showing five of the pieces:
Unfortunately, the sixth piece has gone missing!
Can you figure out what shape the sixth piece is?
Remember, the six pieces must go together to form a 3 by 3 by 3 cube, and they must all be different. You may wish to use multilink cubes like the ones shown in the photo to help you to solve the problem.
Is there more than one possible shape that the sixth piece could be?
Many thanks to Nicola Coe who created the original task on which this problem is based.
