What is the mass, in grams, of the object being measured in the triple beam balance shown below

The mass, in grams, of the object being measured in the triple beam balance shown is:

- 223 grams.

Explanation:

The triple beam balances are based on placing strips on three lines, which allow identifying the weight of the object in question, in this case, the three lines are already in grams (it can be noticed because at the end of each line is the letter 'g' which means grams, since some measure are in Newtons), the first line measures 10 in 10 grams, the second line 100 in 100 grams and the third line 1 in 1 gram, since the first line marks 20, the second the 200 and the third the 3, it can be said that the total weight is 223 grams, if at any time you must use a triple beam scale, remember to start on the middle line, then the first and finally the third, that way you can discard large weights more easily and reach the exact weight of the object.
