Cube
Perimeter, surface area, volume of cube
The best calculator for the cube you’ve ever seen :-)
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).
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
(total length of edges) |
O = | 12 × a | [m] |
| P = | a × a = a² | [m²] | |
| Q = | 6 × P1 = 6 × a² | [m²] | |
| V = | a × a × a = a³ | [m³] | |
| u2 = | a √2 ≈ a × 1,41 | [m] | |
| 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
