**Algorithm 5b:** R U Ri U R U U Ri U

**Goal:** To form four tanks on all front,right,left, and back faces.

Wondering what’s a tank?

**How to do it:**

1) You first need to flip the top face any way until you form two tanks positioned either

1a) opposite from each other – one is your front face and the other your back face. Then,perform Algorithm 5a.

1b) adjacent from each other – on is at your back face and the other at your right face. Then, perform Algorithm 5b.

2) Repeat the Algorithms 5a or 5b until all four sides form a tank.
