Uncle Fei planted some saplings to form a solid square as large as possible. As a result, there were 6 more saplings. Later, 34 more saplings were brought in, which happened to be able to make up a larger solid square. How many trees are there on each side of the outermost layer?
费叔叔把一些树苗栽种成一个尽量大的实心方阵，结果还多出了6棵树苗，后来又运来了34棵树苗，恰好能补成一个更大的实心方阵，那么后来的方阵最外层每边有多少棵树？
