(h; a; H) => ciąg geometryczny
a = ?
H = V / Pp
Pp = a²√3 / 4
H = 240√3 / a²
h = a√3 / 2
==========================================================
(a√3 / 2; a; 240√3 / a²) => ciąg geometryczny
an = a * q [do potęgi (n-1)] => wzór ogólny na enty wyraz ciągu
a² = a√3 / 2 * 240√3 / a²
a² = 360 / a
a³ = 360 więc a = 2 * ³√45
