A Correct answer
Explanation

Volume = Mass / Density = 200 / 11.342 = 17.633... Rounding to 2 significant figures gives 18.

AI explanation

To find the volume of the copper sample, divide the given mass by the density using the formula volume equals mass divided by density. This gives 200 g divided by 11.342 g/cm3, which results in approximately 17.633 cm3. Rounding this value to two significant figures according to standard rounding rules gives 18 cm3.
