(II) Estimate how many books can be shelved in a college library with 6500 m² of floor space. Assume 8 shelves high, having books on both sides, with corridors 1.5 m wide. Assume books are about the size of this one, on average.

Verified step by step guidance

1. Calculate the total length of the shelves that can be accommodated in the library. First, determine the usable floor space by subtracting the space taken up by corridors. Assume corridors run parallel and evenly spaced throughout the library.
2. Decide on the arrangement of the shelves. Since the shelves are double-sided, each row of shelves will need space for a corridor on at least one side. Calculate the number of rows of shelves that can be placed in the usable space.
3. Calculate the total length of shelving by multiplying the number of rows by the length of each row. Remember that each shelf unit has shelves on both sides, so only half the number of rows are needed compared to single-sided shelving.
4. Estimate the number of books per shelf by considering the average size of a book and the length of each shelf. Multiply this by the number of shelves per unit (8 shelves high) to find the total number of books per unit.
5. Multiply the total number of shelf units by the number of books per unit to estimate the total number of books that can be shelved in the library.
