Multiples of 3
Problem Statement:

Use the robot to draw out the first six multiples of 3 in order from least to greatest, creating a spiral square pattern. The blocks are placed out for you in the Workspace, but the values may or may not be correct. Modify the pre-placed blocks so that each drive-forward distance is a multiple of 3.

```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
Problem Statement	Drive the robot the first 5 multiples of
3. Each move will represent a multiple then the robot must
turn right to indicate a new multiple. Three of the five
multiples listed are correct, you will need to correct two
driveDistance blocks. */
