A cigarette is a small cylinder of finely cut tobacco leaves rolled in thin paper for smoking. The cigarette is ignited at one end causing the cigarette to smoulder and allowing smoke to be inhaled from the other end, which is held in or to the mouth; in some cases, a cigarette holder may be used, as well.
The breathing rate, or the number of times that a person breathes in and out in 1 minute, is often checked by health care professionals to determine the health of a person. The normal breathing rate is between 12 and 18 breaths per minute.
There are 60 minutes in an hour, therefore: Breaths per hour = 12 X 60, 15 X 60 = 720 to 900 breaths per hour There are 24 hours in a day, therefore: Breaths per day = 720 X 24, 900 X 24 = 17,280 to 21,600 breaths per day. Just multiply by 60 to get how many breaths in an hour, then by 24 to get number in a day. So it would be between 17,280 (12 * 60 * 24) and 21,600 (15 * 60 * 24), If you use the number 14 (for an average) it would be 20160. Multiply the number of breaths X 60 minutes X 24 hrs.
