Wait, when it says

"

(#1) 6x - 36” 2x6 cut diagonally corner to corner.

(#2) 4x - 24” 2x4

(#3) 6x - 28” 2x4

(#4) 4x - 56” 2x4 for a 60” long box; or 68” 2x4 for a 72” long box.

(#5) 2x - 20” 2x4

(#6) 2x - 26” 2x4 for a 60” long box; or 32” 2x4 for a 72” long box.

(#7) 2x - 28” 2x4 for a 60” long box; or 34” 2x4 for a 72” long box.

(Sides) 2x - 36”x60” or 72” ¾” plywood sheet, depending on length of box.

(Top) 1x - 24”x x60” or 72” 1” plywood sheet, depending on length of box.

(Ends) 2x - 36”x36” ¾” plywood sheet. "

It says #(number) (number)x-(number)"

Is it like # means just the step.

2x/4x/6x means the number of them you need.

20"/26"/28" means how long it needs to be?
