Density of titanium is [tex]4.51 g/cm^{3}[/tex] and mass given is 3.9 lb. First convert mass from pound to gram as follows:
1 lb=453.592 g
Thus, [tex]3.9 lb\rightarrow 3.9\times 453.592 g\approx 1770g[/tex]
Density of a substance is defined as mass per unit volume. Thus, volume can be calculated as follows:
[tex]V=\frac{m}{d}[/tex]
Putting the values,
[tex]V=\frac{1770 g}{4.51 g/cm^{3}}=392.46 cm^{3}[/tex]
Converting the volume into cube inches:
Since, 1 cm=0.3937 inch
thus, [tex]1cm^{3}=0.06102 inch^{3}[/tex]
and,
[tex]392.46 cm^{3}\rightarrow 392.46\times 0.06102 inch^{3}=23.95inch^{3}[/tex]
Therefore, volume of titanium in cube inches will be [tex]23.95inch^{3}[/tex]
