Question: Assume that you have just built a dense B + tree containing 2 0 . The key field for this B + tree index is

Assume that you have just built a dense B+ tree containing 20. The key field for this B+ tree index is a 40-byte string, and it is a candidate key. Pointers 10-byte values. The size of one block is 1010 bytes. The index was built bottom-up using the bulk-loading algorithm, and the nodes at each level were filled up as much as possible. How many records can be accommodated by a 4-level B+-tree?
