I'm sorry, but I don't understand how your listing of "items" relates to some sort of area or to "cleaning" something...?
Hello,
My question is i have several items with same width and height, but different length, for example, (in millimeters)
1, 100 x 10 x 1800, 120 pieces
2, 100 x 10 x 2100, 30 pieces
3, 100 x 10 x 2400, 5 pieces
4, 100 x 10 x 2700, 100 pieces
5, 100 x 10 x 3000, 80 pieces
I want to have at least 24000000 square mm, in average length of 2400mm, and I must clean the shorter length item first.
Could anyone help me, please.
