Dodecahedron Formulas
Volume (\(\small{V}\))
\(\displaystyle V=\frac{ a^3}{4}·(15+7·\sqrt{5})\)
Surface (\(\small{S}\))
\(\displaystyle S= 3 · a^2 · \sqrt{25+10·\sqrt{5}}\)
Circumradius (\(\small{R_c}\))
\(\displaystyle R_c=\frac{a}{4} · \sqrt{3} ·(1+\sqrt{5}) \)
Midradius (\(\small{R_m}\))
\(\displaystyle R_m=\frac{a}{4} · 3 +\sqrt{5} \)
Inradius (\(\small{R_i}\))
\(\displaystyle R_i=\frac{a}{2} · \sqrt{\frac{25+11·\sqrt{5}}{10}} \)
Diagonal (\(\small{d}\))
\(\displaystyle d=2 · R_c \)
Height (\(\small{h}\))
\(\displaystyle h=2 · R_i \)
