In a ballast zone diagram, with grade elevation 1,321 ft and roof height 1,361 ft, and ballast depth factor 0.6, what is the ballast dimension along the fascia for corner zone 3?

Explanation:
In ballast zone diagrams, the ballast dimension along the fascia in a corner zone is found by applying the ballast depth factor to the vertical rise between grade level and roof height. Compute the vertical rise: 1,361 ft minus 1,321 ft equals 40 ft. Multiply by the ballast depth factor of 0.6: 0.6 × 40 ft = 24 ft. So the ballast dimension along the fascia for corner zone 3 is 24 feet.
