3 cups equals how many servings of vegetables?

this new diet plan says i need 3 cups of vegetables about per day. but that's kind of confusing because serving sizes go in ounces. I'm just going by serving sizes. the carrots I'm eating on the bag it said 1 serving equals 3 oz. so i measured out 3 oz on the scale ate them. now, how much of those 3 cups per day I'm supposed to have would you say that is?
