dissent thread to chew on
If each average pack of gum weighs 47.1 grams, holding 15 sticks, and 17% of its weight is due to packaging
Subtract the 17% of packaging weight from 47 grams = 8.00700 grams of packing weight.
Subtract 8.00700 grams of packaging weight from the total
If each average pack of gum weighs 47.1 grams, holding 15 sticks, and 17% of its weight is due to packaging
Subtract the 17% of packaging weight from 47 grams = 8.00700 grams of packing weight.
Subtract 8.00700 grams of packaging weight from the total
47.1 grams = 39.09300 grams of total gum in (15 sticks)
Divide 39.09300 grams x 15 sticks = 2.6062 grams of gum per stick
If 1 Million people line a parade route and each person simultaneously begins chewing one stick of gum weighing 2.6062 grams on average...
Divide 39.09300 grams x 15 sticks = 2.6062 grams of gum per stick
If 1 Million people line a parade route and each person simultaneously begins chewing one stick of gum weighing 2.6062 grams on average...
The total amount of gum being chewed at one given time is 1,000,000 x 2.6062 grams = 2606200 grams of gum
2606200 grams of gum converted to pounds = 5745.687 pounds of gum
One stick of gum.
1 Million people.
5745.687 pounds of gum being chewed at once along a parade route.
