To solve the problem step by step, we need to find the total surface area of the metallic sheet used for the open bucket, which consists of the curved surface area of the frustum of a cone, the area of the circular base, and the curved surface area of the cylindrical base. ### Step 1: Understand the Shapes Involved The bucket is made up of two parts: 1. A frustum of a cone (the upper part). 2. A hollow cylindrical base (the lower part). ### Step 2: Formulas for Surface Areas ...
