Answer:

The height of the great pyramid is:

  • <u>303.6 cubits approximately</u>.

Or:

  • <u>5464.6 inches approximately</u>.

Step-by-step explanation:

The Great Pyramid of Giza could be said to have two heights: one at the time of being built and the other that can be currently measured, however, to answer the question, <u>the current height has been used, which is 303.6 cubits</u> (I give the answer in this unit because it was the one used by its builders).

There is a slight discrepancy with the values given in the exercise: <u>one cubit equals 18 inches, not 20</u>.

What is permutation and combination?

A set of elements can be divided into subsets in two different ways: combination and permutation.

                          The components of the subset may be arranged in any order when combined. The components of the subset are listed in a permutation in a certain order.

If the word has 5 different letters  then it is just 26-choose-5 or (26/5).

If the word has 4 different letters  then it is just 26-choose-4 or (26/4)

have 4 options to choose which letter to duplicate twice.

This gives =  4*(26/4)

If the word has 3 different letters  then it is just 26-choose-3 or (26/3).

you duplicate one of the three letters 3 times - 3 options for that, or you choose 2 letters and duplicate each one twice - again 3 options. In total this gives  = 6*(26/3).

If the word has 2 different letters  then it is just 26-choose-2 or (26/2).

The sets of 2 different letters and duplicate either one of the letters 4 times - 2 options; or duplicate one letter 2 times, and the other 3 times - again 2 options. In total this is  = 4*(26/2).

The word has just 1 distinct letter you have =  (26/1).

we get :

N = (26/5)+ 4*(26/4) + 6*(26/3) + 4*(26/2) +  (26/1)

= 142506
