Cube Calculator

Enter edge length or face diagonal or space diagonal


Cube -  a three dimensional geometrical figure, it consists of six square sides that meet at 8 vertexes. As other regular geometrical figures, it can often be spotted in nature - for example Pyrite crystal is cube shaped.

Equation form:

Face diagonal (d1) =√2 * a
Space diagonal (d2) =√3 * a
Surface Area (SA) = 6 * a²
Volume (V) = a³
Volume (VC) of circumscribed sphere about cube with edge a:
VC =√3 * π * a³
Volume (VI) of inscribed sphere in cube with edge a:
VI =π * a³
Volume (VT) of sphere tangent to edges in cube with edge a:
VT =2 * π * a³
3 * √2
