Final answer:
Each student in class 5 got the same number of chocolates as the total number of students. The total chocolates were 256, and by finding the square root, we know there are 16 students, making option a) 16 correct.
Step-by-step explanation:
The number of chocolates distributed among the students of class 5 is 256, and each student received the same number of chocolates as the total number of students. To find the number of students, we need to solve for a number that, when multiplied by itself, equals 256.
This is essentially finding the square root of 256. The square root of 256 is 16, which means there are 16 students in the class since 16 chocolates per student times 16 students equals 256 chocolates. So, option a) 16 is the correct answer.
