Before the age of technology, the library was overflowing with books! Then, during one decade, each book was stored on microfiche. This new storage space was equal to the cube root of the old space. In the next decade, the microfiche were converted to diskettes. This new storage space was equal to the square root of the previous space. Finally, in this decade, each diskette has been changed over to a compact disc. The current space is about 23% of the previous space. If the current space is equal to 3 books, how many books were in the old library?
