Give the step-by-step reasoning process and then the final answer. Every day, Bob logs 10 hours of work in his office. If he works for five days a week, calculate the total number of hours he logs in a month.
In a week, working 10 hours a day, Bob logs 10 * 5 = 50 hours. After a month with 4 weeks, Bob logs 4 * 50 = 200 hours for his office working hours.
The final answer: 200.
