"구멍의 수" translates to "the number of holes" in English. This concept can refer to various contexts, such as counting holes in objects, like socks or cheese. It can also apply to mathematical problems where one needs to determine the number of holes in a given shape or figure. In geometry, the number of holes in a shape is often related to its topology. For example, a torus has one hole, while a sphere has none. Understanding "구멍의 수" helps in visualizing and solving problems in both everyday life and advanced mathematics.
