The 4th dimension is commonly regarded as time. So a 4D cube could be considered a 3D cube as it exists over time.
We can think time as a 4D object, but we cannot visualize so easily a 4D object. But surely we know that a 4D object cannot live inside the 4D space, it will live in the 5th dimension space. We know that we can calculate the hyper-volumes by using integration (in our case) over a R4 domain which is not so easy to be visualize also. For example by hand we can construct a R3domain by using the xyz-coordinate system.
i think it is where 2d is flat 3d looks like you can touch it but you cant and 4d is where you can see it and physically touch it
It is a linear equation in one unknown, d.
