Isn't a cube by definition a 3 dimensional object? If it were 4 dimensional, it would no longer be a cube.
Its a generalisation. A 4d cube is a shape that has the same length in all 4 dimensions. You can also talk of 5d cubes, 6d cubes, etc. These are commonly called n-cubes: a 4-cube is a 4d cube.
There are also 4D spheres, even though spheres are definitionally 3D. They are called n-spheres.
