第一种情况，URU’R’U’F’UF"远切回回，接孩子放学"
第二种情况，U’F’UFURU’R’"远切回回，接孩子放学。"
第三种情况
需要的棱色块不在顶层，而在第二层的错误位置或者朝向。

在用公式之前，应参照上图顶面黄色的样子来确定魔方 顶层怎么摆。
只要对出十字就好啦，并不需要十字侧面的颜色和下两层吻合。
公式如下，FRUR’U’F’

此步公式共9步，有点长，此步比上步简单，
1、顶面已经对好（概率1/6），
2、一条边两个角有相同的颜色（概率2/3），像以下这些例子，
如果你4条边都是两角颜色相同，那就是已经对好
![](https://wkrtcs.bdimg.com/rtcs/image?w=548&md5sum=dfd9afb5d164c48682a06f92bb9dcd13&sign=cfd4ef78bf&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=83&ipr={"t":"img","w":"548","h":"111","dataType":"png","c":"word/media/image20.png","imgOriW":741,"imgOriH":150})
两角中间的棱颜色和下面两层的颜色我们不用关心。现在把这条边放在右边，我们就可以开始我们的公式了。![](https://wkrtcs.bdimg.com/rtcs/image?w=89&md5sum=dfd9afb5d164c48682a06f92bb9dcd13&sign=cfd4ef78bf&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=83&ipr={"t":"img","w":"89","h":"65","dataType":"png","c":"word/media/image21.png","imgOriW":89,"imgOriH":65})

3、找不到有两角同色的边（1/6的概率）
找不到这样一条有两角同色的边，就直接做一遍上面的公式，哪条边放在右侧都可以，之后就一定可以找到一条两角同色的边， 把这条边放在右侧，然后再用上面的公式就可以了。
