I think the first box on the top is 10 and the bottom is 4. Hope this helped :)
If an items weight is 0 it would be like a peice of paper or cotten ball. when a cotten ball is weighed it does not affect anything. as when a peice of paper is wieghed it moves its meater 1 inch.
Z = k * x
55 = k * 5
divide both sides by 5
11 = x
z = 11x
z = 11 * 12
z = 132
Is there a ratio? bc that doesnt look like the full question
