Hi Torrey,
For the first part, you probably pressed the Y key, which separated the two side Faces from the rest of the Cube.
For the top Face....think about what you're trying to do; a single Face is 2 dimensional. The top Face has a thickness (dimension in the Z-Axis) of 0. Scaling in Z multiplies that thickness of 0 with a scalar value, but multiplying 0 with any number results in 0.
Side note: you're using Left Click Select (that's the default now... it's fine if you want to do that) and when you wanted to Scale the whole Cube in the Z, you accidentally Selected the top Face.
(Also: try and stop using those Active Tools as soon as possible; the Shortcut for Scaling is S. The Active Tools are like those side wheels on bikes; meant for Blender 'babies', so they don't fall over, but actually causing more trouble than being helpful.)
Thanks for the help man i got most of it figured it out! Noticed i had the move the mesh slight then align with Y Key for the axis to scale the whole cube,
Could you explain the "active tools" and how to take them off? I'm using all the hotkeys in the video, but it still changes in my "Toolbar" which is something i noticed that wasn't happening in the video, His tool bar stays on the "select" function and doesn't bring up. The extra stuff, and i like that
