Final answer:
To calculate the total number of class periods for 30 students with 6 classes each, you multiply the number of students (30) by the number of classes (6) to get a total of 180 class periods.
Step-by-step explanation:
The question asks us to calculate the total number of class periods that need to be scheduled for 30 students, each with 6 classes per day. To find the answer, we simply multiply the number of students by the number of classes each student has. This is a basic arithmetic problem involving multiplication.
30 students × 6 classes per student = 180 classes in total that need to be scheduled.
Therefore, the correct answer is C. 180 total class periods need to be scheduled.
