Taking into consideration that each man works an 8 hour work day: (4 x 8) x 48 = 1536 man hours to complete the job for 4 men *** (Men x Man hours per day) x Days Worked = Total Job Man Hours *** 1536 / (3 x 8) = 64 days for 3 men to complete the same job *** Total Job Man Hours / (Men x Man Hours per day) = Days until Job Completion***
That depends on how many men there are. If there is 1 man, then he does 7,000,000 man-hours of work in 7,000,000 hours, or about 798 years of continuous work. If there are 1,000 men, then they do 7,000,000 man-hours of work in 7,000 hours, or about 292 days of continuous work. If there are 100,000 men, then they do 7,000,000 man-hours of work in 70 hours, or about 2.917 days of continuous work. The problem we have with this question is that a "man-hour" is not a unit of time.

No, the plural form for 'man hour', the amount of work that one person can do in one hour, is man hours.
Since we are given no information to the contrary, the following discussion assumes that all men are created equal, and every worker accomplishes the same amount of work in the same amount of time. Since 8 workers can build a cabin in 60 hours, the job comprises (8 man) times (60 hours) = 480 man-hours of labor. That doesn't change. Now however, 480 man-hours of labor must be completed in 32 hours. The number of workers required to accomplish this is (480 man-hours) divided by (32 hours) = 15 man.

man hours are the total amount of hours each employee works. For example, 10 men working one 10 hour shift would be 100 man hours.
man-hours. They have worked a total of 150 man hours. (Not sure about the hyphen)
Make a chart, and for each worker, write down the total number of hours that he or she worked in the three months. Then add up all of those numbers to get the total number of man-hours during the three months. For example: Worker's name Total hours worked Jose 320 hours Jese 400 hours Joan 500 hours Jill 200 hours Jackie 415 hours Jodie 90 hours Jupiter 282 hours Total man hours 2207 hours Obviously, this is a simplified example; since you had up to 20 workers, but just expand on this idea up to the number of workers that you had.
34.5 years = 302,420.541 total hours or 71,760 work hours.
