If the company was producing 7000 toilet paper per day, when it ramped up its toilet paper production three times per day, it produced 3*7000 = 21000 more per day.
The total toilet production by the company increased to 7000+21000 = <<7000+21000=28000>>28000
In March, with 31 days, the company produced a total of 28000*31 = <<28000*31=868000>>868000 toilet papers
