[창의 퍼즐] 첨성대

초등학교 1학년들은 첨성대, 동궁원, 왕릉이나 경주박물관으로 현장체험학습을 간다.(기억 나시죠?)

비가 오지 않아서 첨성대, 동궁원, 왕릉으로 가기로 했다.

40분동안 버스를 타고 첨성대에 도착했다.

수동이는 이 멋진 광경이 인상적이어서 짝퉁을 만들어 보았다.

144층으로 쌓고,

x층에서는 y개의 벽돌을 썼다. x,y의 관계식이 다음과 같다. $y=\left [ 432x ^{2}-\frac{1}{3}x +24 \right ]$

잘 만들었다 싶어서 보는데....문이 없다!

몇 개의 벽돌을 썼을까?
