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,
\(\text{density}=\frac{\text{mass}}{\text{volume}}\)
Volume = 16×2.5×5 = 200 cubic centimeters.
Substituting the known values in the above formula, we get
\(19.3=\frac{\text{mass}}{200}\\\\\text{mass}=200\times19.3\\\\\text{mass}=3860\text{ grams}\)
Hence, mass of the gold bar is 3860 grams.
