Cube Calculator

Calculate cube side length, solid diagonal, volume, and cube area.

How to calculate Cube Side Length

  • Calculate cube side length using face diagonal, solid diagonal, volume or area.

    a = side length
    f = face diagonal
    d = solid diagonal
    V = volume
    S = surface area

    Calculate cube side length using face diagonal:

    a = 2 x
    f
    2

    Calculate cube side length using solid diagonal:

    a = 3 x
    d
    3

    Calculate cube side length using volume:

    a = V1/3

    Calculate cube side length using surface area:

    a =
    S
    6

How to calculate Cube Face Diagonal and Solid Diagonal

  • Calculate cube face diagonal or solid diagonal using the side length.

    Calculate cube face diagonal using side length:
    f = a x 2

    Calculate cube solid diagonal using side length:
    d = a x 3

How to calculate Cube Volume and Surface Area

  • Calculate cube volume or surface area using the side length.

    Calculate cube volume using side length:
    V = a3

    Calculate cube surface area using side length:
    S = 6 x a2
