The density of cadmium metal is 8.642 g/cm³. Given that 1 foot (ft)= 12 inches (in.), 1 in. = 2.54 cm, and 1 pound (lb)= 453.6 g, what is the density of cadmium in lb/ft³? Hint: Remember that when converting derived units, you must convert each of the component fundamental units individually.

To convert the density from g/cm³ to lb/ft³, first convert grams to pounds and cubic centimeters to cubic feet. 1 g = 0.00220462 lb and 1 cm³ = 0.0000353147 ft³. Therefore, 8.642 g/cm³ * 0.00220462 lb/g * (1/0.0000353147 ft³/cm³) = 539.5 lb/ft³.
