Here you have the cube (d):

Code: Select all

+-+
|4|
+-+-+-+-+
|5|1|2|6|
+-+-+-+-+
|3|
+-+

Rotating its front side up, you get:

Code: Select all

+-+
|5|
+-+-+-+-+
|3|1|4|6|
+-+-+-+-+
|2|
+-+

then rotating the new front side right, you get:

Code: Select all

+-+
|5|
+-+-+-+-+
|6|3|1|4|
+-+-+-+-+
|2|
+-+

what is equal to the cube (c).
