and 4 2D cubes

1--------5
| |
| |
| |
a--------e

2--------6
| |
| |
| |
b--------f

4--------8
| |
| |
| |
d--------h

3--------7
| |
| |
| |
c--------g

the idea is to connect the two 3D cubes using the 4 2D cubes as i showed by numbers and letters
the only proglem ppl can't see 4D so for us it's nothing we can't understand how it show be execttly 'cause our world is 3D and not 4D

like if you take a 3D cube and draw it on a paper it will look like some figure in 2D (papre is 2D) but not like cube
we can understand that a painted 3D cube on 2D papre is a 3D figure 'cause our world is 3D and we are used to see all in 3D
