35. (a) Using Appendix D, we have 1 ft = 0.3048 m, 1 gal = 231 in. 3 , and 1 in. 3 = 1.639 × 10 2 L. From the latter two items, we find that 1 gal = 3.79 L. Thus, the quantity 460 ft 2 /gal becomes 2 2 22 460 ft 1 m 1gal 460 ft /gal 11.3 m L. gal 3.28 ft 3.79 L §· == ¨¸ ¨ ¸ ¨ ¸ ©¹ (b) Also, since 1 m 3 is equivalent to 1000 L, our result from part (a) becomes 2 24 1 3 11.3m 1000L 11.3m /L 1.13 10 m .
