7. Find the volume, in cubic centimeters, of a cube of aluminum that has the same mass as the lead in problem 6 (use density from textbook, table 2.9).
[2]
\[
\begin{array}{l}
\text { mass }=11.34 \mathrm{~g} \\
\text { density }=2.70 \mathrm{~g}_{1} 2
\end{array}
\]
\[
\text { volum } e=\frac{\text { mass }}{\text { density }}
\]
\[
v=\frac{11.34 \mathrm{~g}}{2.7001 \mathrm{~cm}^{2}}=4.20 \mathrm{~cm}^{3}
\]
