Side (\(\small{a}\))

\(\displaystyle a= \sqrt[3]{V}\) \(\displaystyle \ \ \ = \sqrt{\frac{S}{6}}\) \(\displaystyle \ \ \ = \frac{d}{\sqrt{2}}\) \(\displaystyle \ \ \ = \frac{e}{\sqrt{3}}\)

Volume (\(\small{V}\))

\(\displaystyle V=a^3\)

Surface (\(\small{S}\))

\(\displaystyle S= 6 ·a^2 \)

Diagonal (\(\small{d}\))

\(\displaystyle d=\sqrt{2}· a\)

Diagonal (\(\small{e}\))

\(\displaystyle e=\sqrt{3}· a\)
