Question

The density of a particular titanium alloy is 5.77 g/cm? What is the density in

kilograms per cubic feet? Remember that 12 inches equals a foot.

Answer 1

163 kilograms per cubic feet.

Step-by-step explanation:

To solve this problem, first we convert 5.77 g/cm³ to kg/cm³:

• 1000 g = 1 kg

• 5.77 g/cm³ *
  `(1kg)/(1000g)` = 5.77x10⁻³ kg/cm³

Then we convert kg/cm³ to kg/ft³, by converting cm³ to ft³:

• 1 cm = 0.394 in

• 12 in = 1 ft

• 5.77x10⁻³ kg/cm³ *
  `((1cm)/(0.394in))^3*((12in)/(1ft) )^3`= 163 kg/ft³

So the density is 163 kilograms per cubic feet.
