Formulas for the triangular double pyramid
Slant height (\(\small{s}\))
\(\displaystyle s = \sqrt{h^2 + \frac{a^2 · cot^2(\frac{π}{3})}{4}} \)
Edge length (\(\small{e}\))
\(\displaystyle e =\sqrt{\frac{s^2 + a^2}{4}}\)
Total height (\(\small{i}\))
\(\displaystyle i = 2 · h \)
Slant area (\(\small{A_s}\))
\(\displaystyle A_s = \frac{a · s }{ 2} \)
Surface area (\(\small{S}\))
\(\displaystyle S = 3 · a·s \)
Perimeter (\(\small{P}\))
\(\displaystyle P = 3 ·a \)
Volume (\(\small{V}\))
\(\displaystyle V = \frac{a^2· h }{2 · tan(\frac{π}{3})} \)
