In any case, you do the right exercises. Dice are the basis, pay attention to which perspective you want to draw. Take a look at the Drawbox page, it is explained wonderfully. On the page "practic drawing this" you have a 3d model of a cube because you can rotate to better understand how the sides of a cube are drawn in perspective. Have fun trying it out.
