The formula to calculate the Seating Capacity (SC) is:
\[ SC = \left(\frac{A}{S}\right) \times \frac{E}{100} \]
Where:
Let's say the total area (A) is 2000 sq ft, the space required per seat (S) is 15 sq ft, and the efficiency factor (E) is 70%. Using the formula:
\[ SC = \left(\frac{2000}{15}\right) \times \frac{70}{100} = 133.33 \times 0.7 = 93.33 \]
So, the seating capacity is approximately 93 seats.
