The density of titanium is 4.51 g/cm3. what is the volume (in cubic inches) of 3.9 lb of titanium?

Density of titanium is and mass given is 3.9 lb. First convert mass from pound to gram as follows:

1 lb=453.592 g

Thus,

Density of a substance is defined as mass per unit volume. Thus, volume can be calculated as follows:

Putting the values,

Converting the volume into cube inches:

Since, 1 cm=0.3937 inch

thus,

and,

Therefore, volume of titanium in cube inches will be
