In a PE class, the whole class is arranged in four rows (the number of people in each row is equal). The position of Xiaofang row is: the sixth from the front, the seventh from the back. How many students are there in this class?

The sixth from the front and the seventh from the back, that is, there are 12 rows
A total of 4 * 12 = 48 students
Because the sixth one in front of Xiaofang, her own row is also included
After the seventh, Xiaofang's own row is also included
So it's an extra row
