    Cube formulas from edge length

    English cube calculator intent centers on edge length, volume, surface area, and diagonals. This page also supports reverse inputs so you can recover edge length from a known volume, area, or diagonal.

    a is cube edge length.

    A is total surface area.

    d is the space diagonal.

    Use one length unit throughout a calculation. Linear outputs use that unit, surface areas use square units, and volume uses cubic units.
