# Units of Conversion: Cubic (Volume) Measure - Problem 2

Basic to the understanding of unit conversion is the understanding of equivalence, the understanding of the multiplicative identity of 1, and how the two are related. For a review of these concepts, click on Review.

You will also need to multiply and reduce fractions. If you have forgotten how to manipulate fractions, visit Fractions for Adults on SOSMath for an in-depth review.

Review the following table of Standard Units of Conversion to see if you can create fractions that have a value of 1. You can click to examples following each table.

Problem 2: Convert 10 cubic decimeters to cubic yards.

Solution:

• From the above table, you can see that there is a link between cubic decimeters and cubic feet.
• Since 1,000 cubic decimeters is equivalent to 35.314 cubic feet, the fraction

is equivalent to 1.

• Write 10 cubic decimeters as

• Multiply:

• Cancel the cubic decimeters.

• From the above table, you can see that there is a link between cubic feet and cubic yards.
• Since 27 cubic feet is equivalent to 1 cubic yard, the fraction

is equivalent to 1.

• Multiply

by 1 in the form

to obtain

• Cancel the cubic feet...

• Simplify: The answer is 0.013079 cubic yard.
