Questions 1) Assuming that each of the following measurements is exact, perform the following addition: 3 m + 7 km + 4 mm + 5 cm = meters ii) Suppose these numbers represent measurements that are no more precise than stated: each contains only one significant figure. What would be the sum of these measurements? (Careful!) 71000 Meters 2) Consider that each of the measurements is uncertain in the last digit (that's why no more digits are given), and is "rounded off " to the last place. For example, the measurement 3.94 m could be as large as 3.945 m or as small as 3.935 m. In either case it would be rounded off to 3.94 m. Determine the maximum possible and the minimum possible volumes. 1 Maximum Minimum L 3.945 3.935 W 2.405 2.395 H 0.6615 0.6605 Volume
