In a B-Tree, each node represents a disk block. Suppose one block holds $8192$ bytes. Each key uses $32$ bytes. In a B-tree of order $M$ there are $M-1$ keys. Since each branch is on another disk block, we assume a branch is of $4$ bytes. The total memory requirement for a non-leaf node is $32 M -32$ $36 M – 32$ $36 M – 36$ $32 M – 36$
