I would like to ask you how to calculate the price of adhesive tape. You'd better give me a list and write it down in mathematics. I'm not good at mathematics. If I can say it out, I'll definitely adopt it. If I don't understand, please don't answer in a disorderly way. I hope there is a God who knows how to ride and how to add,

For example, the length of a tape is 100 meters, the width is 5 cm, and a square meter of tape is 6 cents! According to this calculation, if you use 100x0.5 = 50 (square meter) and then 50x0.06 = 300 points (3 yuan), then the price of the tape is more than 3 yuan. It's just a metaphor. But the thickness of the tape film is not the same, the thickness of the tape is not the same

The length, width and height of the boxes are 47 cm, 37 cm and 19 cm. How many square meters do you need to make 1500 boxes and calculate the surface area into square meters

The surface area of such a box is 2 * (47 * 37 + 47 * 19 + 37 * 19) = 6670 square centimeter = 0.6670 square meter, 1500 * 0.6670 = 1000.5 square meter

Square calculation price!
It's 3.85 meters long and 3 meters high. The price is 9 yuan. How much is the total price
The unit is m

The price should be 9 yuan / m2, total price = 3.85 × 3 × 9 = 103.95 yuan, about 104 yuan
