## Chemistry: The Central Science (13th Edition)

This is a problem utilizing the density formula as a means to obtain the mass of an object. We are given the density of lead, 11.34g/$cm^{3}$, and the radius of the cube, 5 cm, and told to find the mass. First we have to find the volume, using the volume of a cube formula, which is v=pi*$\frac{4}{3}$*$r^{3}$. When we use this formula, we find the volume is 523.6 $cm^{3}$. Now we use the density formula, where density=mass/volume. When we substitute in our known values, we find the mass to be 5937 grams.
