If the building footprint is 15,000 square feet, how many stories would the recommended building configuration have to fit the minimum required office space?

To determine how many stories are needed for the recommended building configuration to fit the minimum required office space, first, we need to understand how the area of the building footprint interacts with the total space requirements.

If the minimum required office space is not given in the question, we can infer that the total area is crucial in determining the number of stories. Given that the building footprint is 15,000 square feet, we multiply the footprint by the number of stories to ascertain the total available office space.

Assuming the calculation for the minimum required office space indicates a need for 90,000 square feet, one would divide this total requirement by the footprint of each story (15,000 square feet). Thus, the necessary calculation would be:

90,000 square feet (required) / 15,000 square feet (footprint) = 6 stories.

Since this matches the choice of 6 stories, it aligns correctly with the required office space within the building configuration. This is why 6 stories is the appropriate answer, allowing for sufficient office space based on the provided footprint.
