**bobpursley**, Monday, January 21, 2013 at 5:06amI dont know why teachers do these problems.

It is a conversion of cm to yards, and grams to lbs.

density=1.32gram/cm^3)*(2.54cm/in)^3*(36in/yard)^3*1lb/454grams

do all that, then

poundsmass=densityabove*1cubicyard

and you have to worry about what is meant by Weigh in pounds: pound mass, or pound force.
