Where to find the various cargo hold dimensions and volumes of transport aircraft, such as the A330-300? What are the dimensions of the cargo hold on the Airbus A330-300? (In order to check the usable space for containers or baggage.)

I'm looking for the internal dimensions of the hold with its subsections in the Airbus A330-300, i.e. length, width and height. What are they? This is in order to understand how much space there is and and how it's divided for standard containers or for baggage in bulk configuration.
I'm looking the value of volumes of the parts of the hold, too.
The [relevant] dimensions of the cargo compartments are published by the manufacturers. For all Airbus planes, visit: Airbus / Airport and Maintenance Planning. You can also search for other manufacturers.

For the requested number of containers, here they are for the A330-300/900 (no need for the volume as the containers are standardized):



The documents also include the locations of cargo doors.
