Answer
About 4%
Work Step by Step
To find the percent error, subtract the approximate value from the exact value. In this problem, the approximate value is given to us: 105.
The exact value can be found using the actual dimensions of the prism:
7.2 $\times$ 4.6 $\times$ 3.3 = 109.296
Subtract the approximate value from the exact value:
109.296 - 105 = 4.296
The percent error is therefore about 4%.
