```
distance = (1/2) * gravity * time^2
```
where:
* distance is the distance the object falls (in meters)
* gravity is the acceleration due to gravity (approximately 9.8 m/s²)
* time is the time the object falls (in seconds)
Plugging in the values we know, we get:
```
distance = (1/2) * 9.8 m/s² * (8 s)²
```
```
distance = 4.9 m/s² * 64 s²
```
```
distance = 313.6 meters
```
Therefore, the object falls approximately 313.6 meters after 8 seconds.
