If a glass prism can cause white light to be dispersed,can a glass block or any other transparent and smooth surface do that too?

You need to have the same situation that you do with a prism: surfaces that aren't parallel, so that the refraction and dispersion are not cancelled out. So if by block you mean a cube or rectangle, you won't see it with the parallel surfaces, but you could with the ones that are 90º to each other.
