Formula for the elongated square bipyramid

Volume

\(\displaystyle V= \left(1+\frac{\sqrt{2}}{3}\right)·a^3\) \(\displaystyle \;\;\;\;≈ 1.4714 ·a^3\)

Surface area

\(\displaystyle S= (4 + 2·\sqrt{3} )· a^2\;\;\;\;≈ 7.4641 ·a^2\)

Height

\(\displaystyle h=\left(\frac{2}{\sqrt{2}} + 1 \right) · a\;\;\;\;≈2.4142 ·a \)
