where is the written explanation? how about 3 in by 4 in and 1 ft is the given, how to solve that?

A cubes angles are constant regardless of location and size so we can choose our points to be anywhere. You do not have to choose the same points but they would be the easiest to work with. Thanks

Thank you !! You just helped a student with one of his homework

why is p(1,1,0) as we dont know whether it is in x,y,z axis or not

Dude you messed up my whole rubiks cube!

Andre De Jesus commented on 29 Oct 2015

You did something wrong :)

Alex J commented on 20 Mar 2015

My middle layer is solved but now my bottom layer isnt solved. What to do?

Andre De Jesus commented on 29 Oct 2015

You must have done something wrong, make sure that when you are making the moves that you're moving the white pieces back to the bottom. Or you may be doing the algorithm incorrectly :)

Is the T necessary sometimes i ended up wit no T's on the side plzz clarify?

Jack Finney commented on 26 Jan 2015

It is necessary yes because that orients it correctly

dude at the end the parity algorithm destroyed the rest of the edge pairs

Rajatkamal Polisety commented on 23 Nov 2015

oh wait nvm i was doing it wrong lol

your voice sounds like mandark from Dexter's laboratory XD I LOVE IT

How can I move the square up or down? I mean, if the square is in the the top layer, and I need it to move to the below right? How?

Anonymous commented on 02 May 2015

thanks :) 

Imran Yaamz commented on 23 Apr 2015

+Anonymous If they're both on the same layer do R' U F' and you're set to go from there. Hope it helps. :)

Efe Alikadıoğlu commented on 23 Feb 2015

how can i rearrange my centers, because now red-blue-white is correct, but white has green on the other face, and bule has orange, red has yellow ???

tallevi2000 commented on 03 Jun 2015

+Efe Alikadıoğlu just do the trick where you flip the right half of the cube until the centers are in the position you need them to be, turn that F face 180 and turn the right half of the cube back (the same amount of turns you did in the other step only this time backwards).again, dont forget to reajust the cube in your hand so that you are looking at the correct face when turning.
