## On the Subject of Coloured Cubes

WHY ARE THEY MOVING??!?

This module initially contains only a pressable screen and three stage light buttons. Press the screen to start.

Pressing the screen reveals nine colourful cubes, each of varying colours and sizes. Select cubes to form sets in three stages to solve the module.

### Sets

For this module, **set** is a group of three like objects with any number of **parameters**, such that *for each* parameter,
its value is either the same, or different for all three objects.

For example, red (200), green (020), and olive (110) form a set while aqua (122), lime (120), and white (222) do not. The parameters in this case are the red, green, and blue ternary components of each colour.

### Solving

#### True Positions

In each stage, first note down the colour and size* of each cube. Then determine each cube’s **true position** using the table below. Use these positions
to determine the parameters of each cube in the next section.

Stage | Notes | True Position |
---|---|---|

1 | None | The position of the cube on the module. |

2 | The cubes will shuffle around** on the module. | The position of the cube on the module in stage one, before shuffling. |

3 | The cubes will have a good time. Ignore their frolicking. |
The position which forms a set with the true positions of the cube in the previous two stages. Use the row and column of each position as parameters. |
