Slant height
\(\displaystyle s = \sqrt{h^2 + \frac{a^2 · cot^2(\frac{π}{n})}{4}} \)
Edge length
\(\displaystyle e =\sqrt{\frac{s^2 + a^2}{4}}\)
Total height
\(\displaystyle i = 2 · h \)
Slant areae
\(\displaystyle A_s = \frac{a · s }{ 2} \)
Surface area
\(\displaystyle S = n · a·s \)
Perimeter
\(\displaystyle P = n ·a \)
Volume
\(\displaystyle V = \frac{2·n· a^2· h }{12 · tan(\frac{π}{n})} \)
