A cube of sodium 15.0 cm on a side weighs 3.28 kg. What is the density of sodium in g/cm³?

First, we need to find the volume V of the cube:
V = s³
   = 15³
V = 3,375 cm³

Then, convert 3.28kg to g :
[tex]3.28 kg [/tex]   [tex] \frac{1000g}{1kg} [/tex]   [tex]= 3,280 g[/tex]

Compute for density:
d = m/v
   =  3,280 g / 3,375 cm³

d = 0.97 g/cm³
