Hi,
Can I use "is" for the following sentence?
Roughly 8-man hours is required for cleaning.
Hours would be followed by the plural "are". Also, your hyphen is in the wrong place. They are not "8-man hours", they are "eight man-hours". I'm not sure if everyone still uses "man-hours". In these politically correct times, I have heard "person-hours" used to denote that a job is not specific to one gender.
I agree. For me, 'are' is fine.I'm okay with the singular verb.
Eight hours is a quanitity, the same way "One hundred dollars is not too much to pay" is a quantity or "three miles is a little far to walk" or "three hours is a little too far for a day trip."
