Explanation:
It is known that [tex]1 g/cm^{3}[/tex] equals [tex]62.428 lb/ft^{3}[/tex]. Therefore, to convert [tex]0.791 g/cm^{3}[/tex] into [tex]lb/ft^{3}[/tex] we multiply [tex]0.791 g/cm^{3}[/tex] by [tex]62.428 lb/ft^{3}[/tex].
Hence, mathematically the calculation will be as follows.
[tex]0.791 g/cm^{3} \times 62.428 lb/ft^{3} \times \frac{1 cm^{3}}{g}[/tex]
= 49.380 [tex]lb/ft^{3}[/tex]
Thus, we can conclude that [tex]1 g/cm^{3}[/tex] equals 49.380 [tex]lb/ft^{3}[/tex].
