Answer:

Mass of the gold bar is 3860 grams.

Step-by-step explanation:

The dimensions of the gold bar is 16 centimeters by 2.5 centimeters by 5 centimeters.

The density of the gold bar is 19.3 grams per cubic centimeter.

We know the formula,

[tex]\text{density}=\frac{\text{mass}}{\text{volume}}[/tex]

Volume = 16×2.5×5 = 200 cubic centimeters.

Substituting the known values in the above formula, we get

[tex]19.3=\frac{\text{mass}}{200}\\\\\text{mass}=200\times19.3\\\\\text{mass}=3860\text{ grams}[/tex]

Hence, mass of the gold bar is 3860 grams.
