Final answer:
After tearing and doubling a 0.1 mm thick sheet of paper 25 times, the stack height would be 3,355.4432 meters high.
Explanation:
The stack height of paper after tearing it and doubling it 25 times can be calculated using exponential growth. Since the paper is 0.1 mm thick initially, after one tearing and doubling, the stack would be 0.2 mm thick. After 25 tearings, the thickness would double 25 times, so we use the formula for exponential growth:
Height = initial thickness × 2number of times doubled
Height = 0.1 mm × 225
To find the result of 225, you would calculate:
225 = 33,554,432
Therefore, the height of the stack would be:
Height = 0.1 mm × 33,554,432 = 3,355,443.2 mm
To convert that into a more manageable unit, like meters:
3,355,443.2 mm = 3,355.4432 meters
So the stack of paper would be 3,355.4432 meters high, which is over 3 kilometers tall!
