Can someone please help with this problem and explain it please? If soil has a density of 1.32 g/cm cubed, then what does 1.0 cubic yards of soil weigh in pounds?

I don't 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.
