A cuboid tea box, 10cm long, 6cm wide and15cm high. There is a circle of trademark paper around. How many square centimeters does this trademark paper need at least?

Because there is a circle of trademark paper around, the scope of pasting is around, and there is no need to paste it up and down.

Because the length is 10 cm and the height is 15 cm, the areas on both sides are 150 cm.

It's 6 cm wide and 15 cm high, so the other two sides are 90 cm square.

So a * * * area is 480 square centimeters.

So the formula is as follows

Solution:

10× 15= 150 (square centimeter)

6× 15=90 (square centimeter)

150×2+90×2=480 (square centimeter)

A: This trademark paper needs at least 480 square centimeters.

If you are satisfied with the answer, please accept it. Thank you.
