# Find density of lead if its relative density = 11.3

$\begin{array}{1 1} (a) \;11.3\;g/cm^2 \\ (b) \;11.3 \times 10^2\;kg/m^3 \\ (c) \;22.6\;g/cm^2 \\ (d) \;11.3 \times 10^4\;Kg/m^3\end{array}$

Relative density $=\large\frac{Density\; of\; substance }{Density\; of\; water}$
Density of water $= 1\;g/cm^3$
$\qquad= 10^3\;kg/m^3$
Relative of density $= 11.3 \;g/cm^3$
or $11.3\;g/cm^2$
