Cube Volume Calculator

Find the volume of a cube from its edge length, plus surface area, space diagonal, and total edge length.

Input

Enter the edge length of a cube to compute its volume, surface area, space diagonal, and total edge length at once.

Edge length a

Volume a³

Surface area 6a²

Space diagonal a√3

6.928203

Total edge length 12a

Lengths use the same unit as your input. Surface area is in squared units and volume is in cubed units.

Volume is the edge length cubed. V = a × a × a = a³, expressed in cubic units of the input length.
Surface area sums the six square faces, so S = 6a², expressed in square units of the input length.
The space diagonal connects the two farthest opposite corners and equals d = a√3, where √3 is about 1.732.
The total edge length is the sum of all twelve edges of the cube, which equals 12a.
Enter a positive number for the edge. Zero, negative, or non numeric values cannot be calculated.
