Layers of cubes
Part 1 Aim: Investigate how many different arrangements there are for five cubes on the bottom layer when the grid size is 2x3. Rule 1: The number of cubes on the bottom layer is one less than the number of squares on the grid. On a grid size of 2x3 squares, there is a possible of 6 different variations using only 5 cubes because all 6 squares have to be empty once. The variations are as follows! Part 2 Aim: Investigate the relationship between number of arrangements and the size of the grid when there are: (a) Two layers of cubes, (b) More than two layers of cubes Rule 1: The number of cubes on the bottom layer is one less than the number of squares on the grid. Rule 2: Each new layer is made with one less cube than the layer underneath it. (a) To find out the formula for 2 layers of cubes, I drew a table, which started from the product of the grid size (G) 3 all the way up to 10. Then in the next column it was the number of cubes on layer 1 (L1), then it was the number of cubes on layer 2 (L2). And the last column was the number of possible arrangements. So from that Table I found the formula for the arrangements of 2 layers to be GxL1, this is because the number of arrangements you could arrange 5 cubes on 6 square grid was 6 times, and the number of ways you could arrange 4 cubes on 5 cubes would be five.
