There is a problem with the methodology of the solution to the Mayan pyramid challenge.

Using 10% of the thickness for each level will result in steps of different sizes and therefore not a 45 degree pyramid

layer 1 = 20

layer 2 = 18 (this is fine)

BUT

10% 0f 18 = 0.9!!

therefore the next strep is smaller and this continues.

In order to get 1 unit steps then the thickness should be set at

Level 1 1/10 (i.e 1 unit out of 10)

Level 2 1/9 (1 unit out of 9)

Level 2 1/8

Level 2 1/7

Level 2 1/6

etc

These calculations can be carries out in the parameter box (i.e. enter ‘1/10’ etc)
