Calculation formula of carton price (total L + 3cm) * (total W + 3cm) / 10000 * square price * 1.1 (L + W + 5cm) * (W + H + 3cm) * 2 / 10000 * square price (L + 2cm) * (W + 2cm) / 10000 * Flat formula square price, under what circumstances are these three used? I don't understand this, but who can explain it?

Calculation formula of carton price (total L + 3cm) * (total W + 3cm) / 10000 * square price * 1.1 (L + W + 5cm) * (W + H + 3cm) * 2 / 10000 * square price (L + 2cm) * (W + 2cm) / 10000 * Flat formula square price, under what circumstances are these three used?

The above formula should be (L + W + 5cm) total length (W + H + 3cm) total width * 2. This is the area of the carton. The unit price is 1.1 yuan, square. It means one. The supplier deliberately said that the difficulty is difficult to understand. It is the ordinary counterpart case (length + style + 8) * (style + height + 4) * 2 * square price
