SAM cubes are condensed Alkagizer. As some people make them in ice cube trays and others in pucks, we generally don't standardize. We say if you make a full blender of Alkagizer, pour it out into trays, count the cubes, divide by 3 and that is an Alkagizer.
Most standard ice cube trays hold 1 ounce per cube so it would be 12 cubes per Alkagizer.
