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)
