Q

A typical book has about 459 000 characters. Your eReader has half a mebibyte of space left on it. Will a typical book fit in the remaining space? Assume 1 character = 1 byte

A

459 000 chars = 459 000 bytes
1 MiB =1024 ×1024 bytes
459 000 chars = (459 000)/(1024 × 1024) mebibytes
This is approx. 0.438 MiB, so the book will fit.
