How many dots ore on a set of dominoes?

I have a math problem, and I need to know how many dots are on a set of dominoes. Thanks!|||A regular "Double Six" set has seven denominations:





0,1,2,3,4,5, and 6.





and there are 7+6+5+4+3+2+1 combos = 28 tiles.





Each averages 3 dots each side = average 6 dots per tile.





6 dots/tile X 28 tiles = 168 total dots.|||Depends on the set - the number will vary depending on if the dominoes go up to double 6, double 9, or double 12.
