Next, make sure you understand the types of problems in Chapter 8.

TYPES OF PROBLEMS

Be able to measure length in both the United States and metric measurement systems. [8.1]
Estimate lengths; choose an appropriate unit for measuring a given length. [8.1]
Find the perimeter, circumference, or distance around a given figure. [8.1]
Solve applied problems involving length. [8.1]
Be able to measure area in both the United States and metric measurement systems. [8.2]
Estimate areas; choose an appropriate unit for measuring a given area. [8.2]
Find the area of a given figure. [8.2]
Solve applied problems involving area. [8.2]
Find the surface area of an object. [8.3]
Estimate volumes; choose an appropriate unit for measuring a given volume. [8.3, 8.4]

Once again, see if you can verbalize (to yourself) how to do each of the listed types of problems. Work all of Chapter 8 Review Questions (whether they are assigned or not).

Work through all of the problems before looking at the answers, and then correct each of the problems. The entire solution is shown in the answer section at the back of the text. If you worked the problem correctly, move on to the next problem, but if you did not work it correctly (or you did not know what to do), look back in the chapter to study the procedure, or ask your instructor. Finally, go back over the homework problems you have been assigned. If you worked a problem correctly, move on the next problem, but if you missed it on your homework, then you should look back in the text or talk to your instructor about how to work the problem. If you follow these steps, you should be successful with your review of this chapter.

We give all of the answers to the Chapter Review questions (not just the odd-numbered questions), so be sure to check your work with the answers as you prepare for an examination.
