### Calculation

Enter a value to any field - the others are calculated themselves. If you change a value in any field, the others are automatically recalculated.
For decimals you can enter either points or commas
as decimal marks (but only one decimal point in a value).

 Side edge a = m Face diagonal u2 = m Space diagonal u3 = m Perimeter(total length of edges) O = m Area of one face P = m² Surface area Q = m² Enclosed volume V = m³ round to 6 digits nm µm mm cm dm m km

The result will be in the units that you enter into the fields.
For example: if you enter centimeters, calculation will be also in centimeters.

If appears an error NaN, check whether you enter to the field
a correct value, ie. without any letters and other characters.

### Formula

 Perimeter(total length of edges) O = 12 × a [m] Area of one side P = a × a = a² [m²] Surface area Q = 6 × P1 = 6 × a² [m²] Enclosed volume V = a × a × a = a³ [m³] Face diagonal u2 = a √2 ≈ a × 1,41 [m] Space/volume diagonal u3 = a √3 ≈ a × 1,73 [m] a … length of one edge

u2 … face diagonal

u3 … space/volume diagonal

S … center of cube

o … axis

### Cube and Sphere

Space/volume diagonal (u3) = diameter of circumscribed sphere
Length of side edge (a) = diameter of inscribed sphere
