Not sure I should provide actual data, but I typically locate that information in the AMM Chapter 6 and the SRM Chapter 53. If you have access to the AMM or SRM you should be able to find them.

The cross sectional diagrams you refer to may be contained in the Liaison manuals for those respective aircraft. You can also find an overview of the aircraft dimensions in Appendix AE of the MPD for Boeing Aircraft.

@debodine, @LiftDivergence and @SparWeb: Thanks for your responses. Got it in Nui's book. cheers.

Further more on this:
Interface control document for the installation of monuments/dividers, provides decompression load as a function of the compartment volume Vs. Ventilation area. For the ventilation area, is it well founded to include the various decompression panel areas and floor level grill exit areas? or just the divider opening area to the airflow?
Cheers.
