Understand that density is defined as mass per unit volume, expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\) with units like g/cm\(^3\).
Recall or look up the known density of lead at room temperature from a reliable source or periodic table reference; lead is a heavy metal with a relatively high density.
Compare the given options to the known density value of lead, which is approximately 11.3 g/cm\(^3\).
Identify which option is numerically closest to this known density value.
Conclude that the correct answer is the value closest to 11.3 g/cm\(^3\), confirming the density of lead at room temperature.
