use dimensional analysis and set up your equation like so:

[tex]450g\ x\ \frac{cm^3}{19.3g}[/tex]

if you do the calculations, the 'g' should cancel out which leaves you with the unit 'cm³'

[tex]cm^3=\frac{450g}{19.3g}[/tex]

[tex]cm^3=23.31606218...[/tex]

= 23.3 cm³

[tex]\text{Density,}~ \\\\~~~~~~~\rho = \dfrac{m}{V}\\\\\implies V = \dfrac{m}{\rho}\\\\~~~~~~~~~~=\dfrac{450 ~g}{19.3 ~ g~cm^{-3}}\\\\~~~~~~~~~~=23.3~ cm^3\\\\\text{Hence, the volume of 450g gold is }~23.3 ~cm^3.[/tex]
