help please, beginner conffuzled

Hello, I was wondering if i could get some help from any grasshopper mastermind / anyone that knows a bit more than me. 

I would like to create a ghx file which will allow me to create the maximum possibilities of outcomes.

I have 8 boxes/rectangle ( this number is a variable and may change). They all have specific dimensions and must remain in the same xyz direction. 

I have a larger bounding box, and i wish to fit my 8 boxes into this larger box ( with specific dimensions). and to achieve the variety of possibilities there is, without the 8 boxes overlapping. 

My problem is I do no know how to allow grasshopper or vb to create the maximum number of possibilities . I am definitely a beginner, but i do understand a little.

Any help would be muchh appreciated. 

Best, 

Mush
