Maximum Number of Rows Occupied
To find the maximum number of rows occupied in the planetarium with a seating capacity of 2000, we need to establish that the number of rows equals the number of columns. Therefore, if we denote the number of rows and columns as "n," the equation becomes:
- n × n = 2000
- n² = 2000
- n = √2000 ≈ 44.72
Since "n" must be a whole number, we take the largest integer less than or equal to 44.72, which is 44. Therefore, the maximum number of rows occupied is:
- Max Rows = 44
Number of Vacant Seats
To find the number of vacant seats when the maximum number of rows (44) is occupied, we calculate:
- Total occupied seats = 44 × 44 = 1936
- Vacant seats = Total capacity - Occupied seats = 2000 - 1936 = 64
Thus, the number of vacant seats when 44 rows are occupied is:
- Vacant Seats = 64
Rows Occupied for 1296 Students
To accommodate 1296 students, we again denote the number of rows and columns as "n." The equation becomes:
- n × n = 1296
- n² = 1296
- n = √1296 = 36
This means that to accommodate 1296 students, the number of rows occupied would be:
- Rows Occupied = 36
In summary, the planetarium can have a maximum of 44 rows occupied, leaving 64 vacant seats, and it can accommodate 1296 students with 36 rows fully occupied.
