A bag of caramel cookies has 20 cookies inside and a box of cookies has 4 bags in total. How many calories are inside the box if each cookie is 20 calories? Let's be accurate as possible.
If 1 bag has 20 cookies and a box has 4 bags, then in total there are 20 * 4 = 80 cookies inside the box. If 1 cookie has 20 calories and there are 80 cookies in the box, then the box has in total 20 * 80 = 1600 calories.
The answer: 1600.
