If an object has a density of 8.65 g/cm^3 and a mass of 346 g, what is its volume in cm^3?
A
29.9 cm^3
B
40.0 cm^3
C
300 cm^3
D
8.65 cm^3

Recall the formula that relates density (\( \rho \)), mass (\( m \)), and volume (\( V \)):
\[ \rho = \frac{m}{V} \]
Rearrange the formula to solve for volume (\( V \)):
\[ V = \frac{m}{\rho} \]
Identify the given values: mass \( m = 346 \) g and density \( \rho = 8.65 \) g/cm\(^3\).
Substitute the known values into the volume formula:
\[ V = \frac{346}{8.65} \]
Perform the division to find the volume in cm\(^3\). This will give the volume of the object.
