In Exercises 7–12, use the following information. The metric system is based on three different units:

• the gram (1 gram = 0.0022046 pound)

• the meter (1 meter = 39.37 inches)

• the liter (1 liter = 61.025 cubic inches)

Other units are formed by adding the following prefixes to these basic units:

• kilo-, which means one thousand (for example, 1 kilometer = 1,000 meters)

• centi-, which means one hundredth (for example, 1 centimeter = 1/100 meter)

• milli-, which means one thousandth (for example, 1 millimeter = 1/1,000 meter)

Use dimensional analysis to convert

a. 1 cubic inch to liters (Round off to the nearest thousandth.)

b. 386 cubic inches to liters (Round off to the nearest tenth.)
