If you’re looking at Rubik’s Cube solutions and your case does not correspond to any of those represented, then your cube in unsolvable.
Why there are Rubik’s Cubes that can’t be solved
Most of the times, the Rubik’s Cube becomes unsolvable because someone, intentionally or unintentionally, takes one or more pieces out of the cube. If the piece is now put back in the cube in a different position or orientation, the cube will now be impossible to solve.
How to fix the Rubik’s Cube
In order to fix the cube, you need to take out the pieces that are not properly in place and put them back so that the cube is fully solved. Therefore, it is advisable to solve most of the cube, so you don’t have to remove and replace so many pieces.
To take out the pieces of the cube, turn 45 degrees one face (see photo). Put a thumb on each edge and make pressure in opposite directions.
Once you have taken out an edge, it’s easy to take out the rest of the pieces you need to change. Now, put the pieces back in the cube, but this time in the correct position. Finally, you have to insert the last edge with a face rotated 45 degrees (just like you did to take it out).
You can now scramble the Rubik’s cube and you will be able to solve it! (if you know how, hehe)
