Answer 1

It’s the whole sides rotating. Create a div partition for each layer on each side. 3 layers per side. Every layer will consist of partition; simply I mean for the top phase 3 layer and 9 partitions. Combine all of them to transform throught left,right,front,etc clockwise and anticlockwise.
