Thomas calculates the volume of an object by multiplying the measurements 1.74 cm x 2.3 cm x 3.09 cm. Using significant figures, how should the answer be reported?

12 cm³

Explanation:

Always round to the place of the number with the least amount of significant figures.

1.74 and 3.09 have three significant figures. 2.3 has two significant figures. Therefore, the answer will be rounded to two significant figures.

1.74 cm × 2.3 cm × 3.09 cm = 12.36618 -> 12 cm³

(The 3 in the tenths place is less than 5 so drop it and all the numbers to the right of it.)

Hope that helps.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
