수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
나는 학원을 갔다 온 후 너무 피곤해서 잠이 들어 버렸다.
깨어나보니, 나는 어떤 작은 행성의 침대 위에 있었다. 60발자국만 가면 반대편으로 갈 수 있는 행성.
- 여기서 이 행성을 구로 나타내고 한 발자국을 1πm라고 하면, 이 행성의 겉넓이는?
나:?????뭐지? 나 숨은 쉴 수 있는건가?(아 당연히 말을 할 수 있으면 숨을 쉬는 거겠지)
근데....여긴 어디지?
주변을 둘러봤더니 어떤 작은 건물이 한 채 있었다.
나는 뭐 할 수 있는게 없었기에 일단 춥지도 않지만 추위를 피하기 위해 건물 안으로 들어갔다.
안쪽에는 방문이 하나 있었는데 들어가려고 보니 잠겨있었다.
다시 보니 그 문 옆에는 비밀번호를 누르는 곳이 있었다.
그래서 벽 쪽을 봤는데 어떤 암호같이 생긴 게 적혀있었다.
3D+2D=?
hint: 16
나는 그걸 보자마자 수업시간에 배웠던 게 생각났고 바로 비밀번호를 풀고 방안으로 들어갈 수 있었다.
두 문제를 다 맞춰 주세요 간단한 풀이도 써주시면 좋아요!
-
오랜만에 문제를 냈네요 스토리 형식으로 문제를 한 번 내보고 싶었어요!
난이도는 아주 낮으니 누구나 풀 수 있을 것 같아요

흐에? 60발자국만 가면 반대편인 행성에 건물을 지을수 있나여?!
-
네 완전 작은 건물이요ㅎㅎ (그리고 그냥 이야기잖아요)
좋아요0
