Cube Volume Calculator
Calculate cube volume, surface area, face diagonal, and space diagonal from edge length, volume, surface area, or space diagonal.
Cube volume from edge length
English results for cube volume calculator usually expect a direct edge-length workflow plus surface area and diagonal outputs. This page keeps edge length as the default input and supports reverse modes when volume, surface area, or space diagonal is known.
a is the cube edge length.
S is total surface area across all six square faces.
d is the space diagonal from one vertex to the opposite vertex.
Outputs
| Output | Use |
|---|---|
| Volume | Capacity or space inside the cube. |
| Surface area | Total outside area of all six faces. |
| Face diagonal | Diagonal across one square face. |
| Space diagonal | Diagonal through the solid cube. |
