A writer is setting a goal to write 6 pages a day, 6 days a week, for 6 weeks. How many pages will be written by the end of the 6 weeks?

The writer is setting a goal to write 6 pages a day for 6 days a week, so the writer will write 6 pages x 6 days = <<6*6=36>>36 pages in a week.

Therefore, the writer will write 36 pages/week x 6 weeks = <<36*6=216>>216 pages by the end of the 6 weeks. Answer: \boxed{216}.
