Acho que deve ser uma brincadeira.
Mas, ... vamos lá:

h = Raíz( 36 / Raíz(3) )
h = 4,5590141139095552839871265039273

h = raiz de (36 / (raiz de 3))
h = raiz de (36 / 1,7250)
h = raiz de (20,78521)
h = 4,5590141139

2h²√3 = 72
2h² = (72√3):(√3)²
2h² = (72√3):3
h² = (24√3):2
h² = (12√3)²
h² = 144.3
h ~= 20,78

h=72/2∙√3=2∙√(3∙√(3))
