Bill had to finish a project from work that was to take him 4 days. If he took 6 seven-hour naps in the four days, how long did he spend working on the project? Give me reasons, before answering the question

Since a day has 24 hours, the project was to take 24 * 4 = 96 hours. Bill took 6 seven - hour naps during the four days, a total of 6 * 7 = 42 hours. The time he spent working on the project is 96 - 42 = 54 hours. So the final answer is 54.
