You're absolutely correct. Unfortunately. Perhaps I'm too much of an optimist and would assume that someone only two+ years from graduation from high school would know the meaning of the word "dimensions".
Then again I spent nearly 30 minutes explaining the fact that the value of a dime is not "10" .. without units .. "10 What" I ask?
They had no clue that a dime was actually $0.10 ... that if you count a stack of dimes you DO NOT multiply by 10 to find out how many dollars one has. Even gave 'em an example ... suppose you have 50 dimes, you multiply by 10 you get 500. So, you have 500 dollars?
Don't ask me what the response was ... you'd be as depressed as I was.
