Question

You are determining the mass of an object using a triple beam balance. When the pointer is lined up with the zero mark, the riders show values of 300 grams, 20 grams, and 8.0 grams. What is the mass of the object?

Answer 1

The mass of the object is 328.0 grams.

When determining the mass of an object using a triple beam balance., the pointer is lined up with the zero mark, the riders show values of 300 grams, 20 grams, and 8.0 grams.
then,
Mass = 300 grams + 20 grams +  8.0 grams (Just find out by calculating manually as well if you dont want to take the help from reader scale)
          = 328.0 grams.

Answer 2

The mass of the object measured using a triple beam balance is 328.0 g.

The triple beam balance is an instrument used to measure mass with great precision (see attached picture). One beam reads 100 g increments, another reads 10 g increments and the last reads 0 to 10 g increments. When the pointer is lined up with the zero mark, the mass of the object is equal to the sum of the masses indicated by the beams.

$m = 300 g + 20 g + 8.0 g = 328.0 g$

The mass of the object measured using a triple beam balance is 328.0 g.
