The fourth dimension is that of movement. When you go someplace in your automobile, you are advancing in the fourth dimension. As a person exchanges energy for time, they progress fourth-dimensionally.
When a mass reaches the speed of light, the mass converts into electromagnetic radiation, and at that time it would have reached the singular dimension of the fourth. Strange as it may seem, at that time everything would become one-dimensional and time would no longer exist. Were all the mass of our universe to be reduced to that of electromagnetic radiation, the universe would have become one-dimensional - time would be no longer. It takes the feature of three-dimensional mass to form physical time.

I know the first 3, but not the 4th. The first 3 (relative to a box) are
1: a line
2: a square (a face of the cube)
3: the cube

Time is on my mind...yes it is....
(Sorry. Since so many people already answered the question correctly, I thought I would put the answer with a bit of silliness).
