A regular trash can in the park typically requires about 1-2 sheets of metal to be constructed. The exact amount of sheet metal needed can vary depending on the size and design of the trash can. However, most standard-sized trash cans can be made from a single sheet of metal, while larger or more complex designs may require additional sheets. **

The amount of sheet metal required for a normal trash can in the park can vary depending on the size and design of the trash can. However, on average, a standard-sized trash can in the park may require approximately 1-2 square meters of sheet metal. This estimate includes the body of the trash can, the lid, and any additional components such as handles or decorative elements. Ultimately, the exact amount of sheet metal needed will depend on the specific dimensions and specifications of the trash can being manufactured. **
