I also have cube with area of 35m^2, with volume of 121 M^3.
I’m planing to insert about 370 “cubes” like this in the big volume, and i want to see how thus cubes would be arranged in the volume.
what should i do in order to get it?
I would suggest a controlled Voxel creation (C# shown below does a recursive Box subdivision and is real-time [more or less]). This appears easy … but maybe could become quite tricky.
Simple: given a Mesh/Brep List and having either a Box module in mind (with given dimensions) or a Box Subdivision Policy you can “divide” items in the List and get a collection of Boxes that “fit” on a per List item basis.
So the “fit” is - somehow - the inverse of what you have in mind: Is made by subdivion (recursive) instead of some other Method.
Obviously the whole approach is designed in order to work with any Geometry: say a Blob, a BrepFace … or even a linear Curve (in this case we can talk about a 3d “pixelization” of a Curve) .
BTW: Maybe using 3D Curves could make the whole approach more clear:
