A file has 40,000 Student records of fixed-length. Consider a disk with block size B=512 bytes. A block pointer is 8 bytes long and a record pointer is 7 bytes long. Each record has the following fields:

Attributes	Size (in bytes)
StudentID	9
Name	30
Sex	1
CourseMajor	10
Phone	9
Address	30
DoB	8
Status	3

1. Calculate the record size R in bytes.
2. Calculate the blocking factor bft and the number of files blocks b assuming an unspanned organization.
3. Suppose the file is ordered by the key field StudentID and we want to construct a primary index on it. Calculate the index blocking factor bft_i.
