I'll solve this step by step using precise LaTeX formatting:

Step 2:
: Define the given quantity

1 \text{ sextillion} = 10^{21} \text{ seconds}
Let's first understand how many seconds are in a sextillion:

Step 3:
: Calculate seconds per year

60 \times 60 \times 24 \times 365.25 = 31,557,600 \text{ seconds/year}
We know there are: - 60 seconds in a minute - 60 minutes in an hour - 24 hours in a day - 365.25 days in a year (accounting for leap years) Total seconds per year:

Step 4:
: Divide sextillion seconds by seconds per year

\frac{10^{21} \text{ seconds}}{31,557,600 \text{ seconds/year}} = 31,674,979.27 \text{ years}

Final Answer

A sextillion seconds is approximately 31.7 million years.
