A student is given the question: "What is the mass of a gold bar that is 7.379 × 10–4 m3 in volume? The density of gold is 19.3 g/cm3."

The student obtains the answer through the following calculation:

answer=7.379×10^−4 m^3×(100 cm/1 m)^3×19.3 g/cm^3

For the above calculation, identify each value as one that is uncertain or known exactly. Then, determine how many significant figures you should report the answer to.
What is the answer? Write your answer to the correct number of significant figures.
