    Rectangular prism volume, area, and diagonal

    English intent favors rectangular prism and box wording. The calculator uses length, width, and height as the core workflow, then reports volume, surface area, face areas, space diagonal, and total edge length.

    l, w, and h are length, width, and height.

    A is total surface area across all six faces.

    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.
