6. If Mr. Q is drinking four (12-oz) cans of beer each day in addition to his normal food intake, how much weight will he gain in 6 months (180 days) ? Assume that 3,500 kcalories consumed in excess leads to one lb of fat gain.

0.00001128 lb fat gain.

Explanation:

4 * 12 ounce of beer = 1 day

In 180 days,

48 * 180 ounce of beer in 3 months.

= 8640 ounce

But 1 ounce = 0.00457 gram calorie

8640 ounce = 8640 * 0.00457

= 39.5 gram calorie in 180 days.

But, 3500 kcalorie = 1 lb fat gain

1 calorie = 1/3,500,000 lb fat

39.5 calorie = 1/3,500,000 * 39.5

= 0.00001128 lb fat gain.
