Cube (Solid) Calculator
Compute volume, surface area, face diagonal and space diagonal of a cube.
About Cube (Solid) Calculator
A cube has 6 square faces, 12 equal edges, and 8 vertices. Volume = s³, surface area = 6s², face diagonal = s√2, space diagonal = s√3.
Formulas
Volume
V = s³
- s
- Edge length
Space Diagonal
d = s√3
- s
- Edge length

Assumptions and limits
- The result is derived only from the single input listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is this different from the cube (x³) calculator?
This calculator computes geometric properties of a cube-shaped solid. The x³ calculator simply raises a number to the third power.
How many edges does a cube have?
A cube has 12 edges, all of equal length.
