What is the volume (in cubic inches) of 3.6 lb of titanium?

22 cubic inches

Explanation:

We are given;

Mass of titanium = 3.6 pounds

We are required to determine the volume of titanium in cubic inches

We need to know the density of titanium;

Density of titanium = 4.51 g/cm^3

1 pound = 453.592 g

therefore, 3.6 pound = (3.6 * 453.592 g per pound)

= 1632.93 g

Therefore;

Volume = Mass : density

= 1632.93 g : 4.51 g/cm^3

= 362.069 cm³

But, 1 in³ = 16.387 cm³

Therefore;

Volume = 362.069 cm³ : 16.387 cm³ per in³

= 22.095 in³

= 22 in³

Thus the volume of titanium is 22 cubic inches
