Question

What is total number of black dots on a dice cube?

Answer 1

anytime you have a solution like that take the highest number in the run and then times it by half that number plus .5. so seeing as how th highest number on the dice is 6 you multiply 6 by 3 + .5 , meaning 3.5. 6 X 3.5 is 21. if you had a run from 1 thru 15 you would multiply 15 by half or 7.5 plus the .5 equalling 8 and making it 15X8 which equals 120. Remember this simple formula for the rest of your life.

Answer 4

The general formula is:

Σ{k=1..n} k = [(n)(n+1)] / 2

For a 6-sided dice:

Σ{k=1..6} k = [(6)(7)] / 2 = 21

Answer 5

1+2+3+4+5+6=21

Why do you ask??????

Answer 6
