The 3-Act task soda can display and it is a class math problem and the first question was what do you see on the display and I saw the Olympic Rings and the word USA and the second one was how many boxes and cans and this is how we solved it there was 23 boxes across and 7 down and it equaled 138 and that was just one half and the other one was the same and we doubled it and there were 321 boxes and there were 45 leftover and we added it to 321 and it equaled 366 and there was 12 cans in each box so we multiplied it with 366 and it equaled 4,404 cans and here’s my video.
