Hello everybody. Though it is a good idea to follow the instructions to get more accustomed to the program and all of its features. If anyone wants another alternative that may not already know. I found by; selecting the right face of the cube and pulling it out to the length I wanted, then selected top left vertices and then bottom left vertices, then to the left in the tools menu, you will see below ‘Merge’. Clicking on this and selecting merge to last. Repeat on the other two vertices on that face and WA-la, a wedge. Just another path to the same destination.
