There are a bunch of chess pieces, and if they are arranged in a square matrix (that is, there are the same number of chess pieces in each row and column), there are still 14 more chess pieces. Chess pieces, how many pieces are there in this pile?
有一堆棋子，把它们摆成一个正方形方阵(即每行、毎列的棋子同样多)，还多14枚棋子，如果摆成比原来那边多一枚棋子的方阵，还差11枚棋子，这堆棋子共有多少枚？
