Answer:
583,200 units
Step-by-step explanation:
Practical capacity per unit = 900 units per hour
Hours per shift = 8 hours
Number of hours worked each day = 3 shifts * 8 hours = 24 hours
Number of days of operation in a month = 27 days
Practical capacity for the month = 900 * 24 * 27 = 583,200 units
