    The calorie content of a serving of this cereal is 140.7 cal.

    Explanation:

    We need to multiply the amount of calories per the amount of each nutrient.

    Proteins: 3 g and 4.1 cal/g ∴ 3 x 4.1 = 12.3 cal

    Carbohydrates: 18 g and 4.1 cal/g ∴ 18 x 4.1 = 73.8 cal

    Fats: 6 g and 9.1 cal/g ∴ 6 x 9.1 = 54.6 cal

    Now we just need to add the amounts:

    Total calorie content = 12.3 + 73.8 + 54.6 = 140.7 cal
