To find the amount of cloth required to cover the lampshade, we need to calculate the curved surface area of the cylindrical frame of the lampshade, taking into account the additional margin for folding over the top and bottom. ### Step-by-Step Solution: 1. **Identify the given dimensions:** - Base diameter of the lampshade = 20 cm - Height of the lampshade = 30 cm - Margin for folding = 2.5 cm (top) + 2.5 cm (bottom) = 5 cm ...
