Note: Homework Hints are given only for the Level 1 and Level 2 problems.
However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
There are many sources for homework help on the internet.

Count the number of cubes to use the definition of volume. See Example 4.
To find the volume of a cube, cube the length of the side. See Example 5a.
To find the volume of a box, find the product of the length, the width, and the length. See Examples 4 and 5.
Look at the gradations on the measuring cup. See Example 7.
These problems are designed to help you estimate capacity. Don’t be afraid to guess, check, and then revise, if necessary. You might also want to look at Example 3.
These problems are testing your knowledge of the metric system.
First find the volume of the pool, and then calculate its capacity. See Example 9.
See Example 1; calculate the areas of each of the faces and then add these areas. Note the top is included in three of these problems, and is excluded in the other three.
Find the area of the cylinder and add the area of the bottom. See Example 2b.
See Example 1; calculate the areas of each of the faces and then add these areas.
Choose the appropriate formula to find the requested capacity. See Example 8.
