수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
페렐만 : 아아~~ 화요일이다!! 7교시 힘들어...
야우심통 : 힘내 이제 점심시간이잖아!
페렐만 : 같이 먹을래?
야우심통 : 그래!
페렐만 : 야우심통아, 그런데 우리가 지금 급식판을 넓이가 일정한 직사각형 모양 책상에 놓고 있잖아...
야우심통 : 그렇지.
페렐만 : 그러면 급식판이 책상 밖으로 나가지 않는다고 하면, 일정한 넓이의 급식판을 배치할 수 있는 최적의 배치법은 무엇일까?
야우심통 : 조건이 부족한데???
페렐만 : 좋아. 그러면 책상의 가로가 32cm, 세로가 28cm이고 급식판의 가로가 10cm, 세로가 8cm이라면 최대 몇 개의 급식판을 놓을 수 있을까?
야우심통 : ...너무 쉽잖아...
페렐만 : 자, 그렇다면 위의 조건에서 급식판이 최대 10제곱센티미터까지 책상 밖으로 나갈 수 있을 때, 최대 몇 개나 놓을 수 있을까?
야우심통 : ...음...그림그리면서 조금 생각해보면 풀겠네..
*책상은 한 개이다.
