1 \begin{problem*}{1.15}
2 A solid piece of led has a mass of $23.94\U{g}$ and a volume of
3 $2.10\U{cm$^3$}$.  From these data, calculate the density of lead in
4 SI units (kilograms per cubic meter).

8 \begin{equation}
9   \rho = \frac{m}{V}
10     = \frac{23.94\U{g}}{2.10\U{cm$^3$}}
11       \cdot\frac{1\U{kg}}{10^3\U{g}}
12       \cdot\p({\frac{10^2\U{cm}}{1\U{m}}})^3
13     = \ans{11,400\U{kg/m$^3$}}
