Mr. digit wanted to assign a number to each student in his class. He could only use the digits 2, 3, and 6 and each student's number had to have three digits. Can he find enough numbers for all 25 students if repeated numbers are allowed? Will there be any extra numbers?

Each student's number has 3 digits, and there are 3 possible digits (2, 3, and 6). How many possibilities are there?
