Slant height
\(\displaystyle s= \sqrt{\frac{1}{4} · cot^2\left(\frac{π}{n} \right) · ( a - b )^2 + h^2} \)
Edge length
\(\displaystyle e =\sqrt{\frac{4 · s^2 + ( a - b )^2 }{4}}\)
Base and top area
\(\displaystyle A = n · \frac{a^2 + b^2}{4 · tan(\frac{π}{n})} \)
Slant area
\(\displaystyle A_s = \frac{(a + b) · s}{2} \)
Lateral Surface
\(\displaystyle A_m = n · A_s \)
Surface
\(\displaystyle S = A+ A_m \)
Perimeter
\(\displaystyle P = n ·a \)
Volume
\(\displaystyle V = \frac{h}{3} · \left( \frac{n ·( a^2 + b^2) }{ 4 · tan(\frac{π}{n})} + \sqrt{\frac{n^2 · a^2 · b^2}{(4 · tan(\frac{π}{n}))^2}} \right) \)
