Y=x^2  NO!. Meters does not equal meters squared.  Try Y=kx^2  where k is a unit conversion factor ie 1/(1meter).In cm,  the k would be 1/(100cm)  Make SURE your equation is dimensionally correct BEFORE you work with it.  The constant k also appears in the answer making volume be in meters cubed (or cm cubed) as volume should be.  This lecture was a mess and should be redone!####[['lecture', 'Course_General_Feedback', 'NEG']]
