1 answer

To calculate the total kilocalories for fats, you need to know the caloric value of fats per gram. Fats have a caloric value of 9 kilocalories per gram.

Total kilocalories for fats = (40g + 13g + 10g) * 9 kilocalories/gram

Total kilocalories for fats = 63g * 9 kilocalories/gram

Total kilocalories for fats = 567 kilocalories

Rounding off to the tens place, the total kilocalories for fats is 570 kilocalories.
