Answer / pratap gangula
The number of rows in a fact table depends upon the grain of the fact. Dimensions can only describe the data in the fact table. Adding more dimensions will not increase the number of rows unless it impacts the grain of the fact. e.g You have fact at the granularity of day and u want to now add time intervals dimension.... this will increase the number of rows in fact.

Answer / asha
Number of rows wouldn't increase. Number of cloumns will
increase in fact table as we will have to store the keys of
those dimensions.

Answer / itesh
Yes, if we increase the dimension obviously that key need
to added in the fact ,
Ex
1 fact joined 1 dim of 4 key,
I have added 1 dim with 2 keys
Now my fact will be 8 keys.
