Attached is a picture from my textbook.
Here is my question:
Must the 3.18cm(1.25in X 2.54cm) have to be cubed(^3) in order to cancel the cm in the 1cm^3 that is beneath the 22.59g Osmium?
Is that a standard rule in algebra? And if it is, under what section might I find it.
I've looked in Blitzer's 6th edition of Introductory Algebra for a clue but didn't find anything there. I've checked out Principles of General Chemistry by Martin S. Silberberg for a similar conversion but didn't find anything similar; all there was in that chemistry text book were much easier conversions.
I've even gone onto youtube and searched "multiplying fractions with unit and exponents" but couldn't find anything.
I find it strange that the entire cm^3 doesn't cancel out and just the cm does.But cubing the 3.18cm is necessary to arriving at the given answer. I could assume that the 1cm^3 should be cancelled, but we cannot cancel the cm^3 on one side and not cancel the cm^3 on the other side, but if we did that, we would be removing the ^3 which is necessary to arriving at the given answer.
Thank you all
