Answer:

11 stories apart

Step-by-step explanation:

We let the "ground" be considered at height = 0

Anything above, is POSITIVE direction

Anything below, is NEGATIVE direction

8 stories are ABOVE, so that would be considered

+8

3 stores are BELOW, so that would be considered

-3

THe difference in height between them is:

8 - (-3) = 8 + 3 = 11

So, that is 11 stories apart (top and bottom)
