About this calculator
A cube is a regular hexahedron: a three-dimensional solid with six identical square faces, twelve equal edges and eight vertices. Because every edge has the same length, its volume is the edge cubed and its surface area is six times the area of one face.
The space diagonal runs from one corner to the opposite corner through the interior of the cube and equals the edge multiplied by √3 (about 1.7321). Cubes are the basis of volume measurement and appear constantly in packaging and 3D modeling.
Frequently asked questions
Raise the edge length to the third power (s³). A cube with edge 4 has a volume of 64 cubic units.
It is the longest internal line, from one corner to the opposite corner, equal to s × √3. For an edge of 4 it is about 6.93 units.
A cube has 6 square faces, 12 edges of equal length and 8 vertices. The total surface area is 6 × s².
