There are 6 letters in word MONDAY.

Therefore, words that can be formed using all 6 letters of the word MONDAY.

Hence, the required number of words formed using 6 letters at a time   =^6P_6

                                                                                            =\frac{6!}{(6-6)!}

                                                                                             =\frac{6!}{(0)!}

                                                                                             =6\times 5\times 4\times 3\times 2\times 1

                                                                                             =720
