In the previous problem, you saw that lyd? = 9ft. Also: 1ft? = 144in", and 1m? = 10000cm2. We can use these relationships to convert between units in area and volume problems. Suppose you want to convert 342ft? yd?. Set up the ratios below and multiply them: (3420*) (1yd") n) (1) yd? Notice how the ratios are set up so that the units ft" will cancel (divide) out, and leave the remaining noun or unit as yd?. Similarly, suppose you want to convert 1584in? ft. Set up the ratios below and multiply them: (in) in*) (1584in²) (1) ft2
