The sheet also includes a second vertical rib that extends in the first direction along the sheet, between the first and second edges of the sheet. The second vertical rib also protrudes in the second direction out of the plane. The sheet further includes a first horizontal rib that extends in a third direction along the sheet between the third and fourth edges of the sheet, and protrudes in a fourth direction opposite said second direction.
