To calculate the quantity of brick or block you need to know what size block or brick you want - the unit dimensions that matter to your quantity is length and height - width won't change the quantity, only the width of the wall you are building.

NOTE: Masonry units are always called in this order by width x height x length, so an 8x8x16 is: 8" wide x 8" high x 16" long!

You will also need to know the length and height of the wall.
