Without actually performing the calculations indicated,tell to how many significant digits the answer to the calculation should be expressed. (0.1 96)(0.08215)(295)/(1.1) (4.2 15 + 3.991 + 2.442)/(0.22) (7.881)(4.224) (0.00033)/(2.997) (6.2 19 + 2.03)/(3.1159)
For these questions, be sure to apply the rules for significant figures. a You are conducting an experiment where you need the volume of a box; you take the length, height, and width measurements and then multiply the values together to find the volume. You report the volume of the box as 0.310 m1. If two of your measurements were 0.7120 m and 0.52145 m, what was the other measurement? b If you were to add the two measurements from the first part of the problem to a third length measurement with the reported result of 1.509 m, what was the value of the third measurement?
