Answer=0.28357114 lb/ft
conversions needed:
30.48cm=1ft
1lb=453.592g
now we can write the following equation...
[tex] \frac{4.22 g}{1 cm}* \frac{30.48cm}{1ft}* \frac{1lb}{453.592g} =[/tex]
cm and g cancel out, leaving us with pounds over feet. now lets solve it...
[tex] \frac{4.22 g}{1 cm}* \frac{30.48cm}{1ft}* \frac{1lb}{453.592g} = \frac{128.6256lb}{453.592ft}=0.28357114 lb/ft[/tex]
