Sketch 8 cubes for me with void spaces connecting to each other when put together as a whole

considering the concepts of induction and deduction, design 8 cubes with emptiness. The cube you will design should contain solid and voids with paths connecting to each cube which can be considered a path of movement inside the cube. the parts subtracted from it and it should contain design principles. while each cube creates a whole seperately, a total of 8 cubes should form a new whole (which cannot be understood when separated) when they come together. each cube model should be 25x25cm, 8 of them should come together to form a 50x50cm cube.
