The Gnostic is correct:
3m = 300cm, divide by 100cm to get 3
180cm divide by 20cm to get 9
50cm divide by 50cm to get 1
Number of blocks needed: 3 * 9 * 1 = 27

The first block size has a side of 40cm which is not a factor of any of the three sides of the stage. This would have wasted area.
The second block size can build the stage with exactly 27 blocks.
