How do you convert cubic feet to cubic yards?

1. Multiply by 27

2. Add 27

3. Divide by 27

4. Square the result

The correct answer is: Divide by 27

To convert cubic feet to cubic yards, the correct method is to divide by 27. This is because one cubic yard is equal to 27 cubic feet, as the yard is three times the length of a foot in each dimension (length, width, and height). Therefore, when you have a volume measured in cubic feet, you can find the equivalent volume in cubic yards by performing the calculation of dividing the total cubic feet by the number of cubic feet in a cubic yard, which is 27. This conversion is essential for various applications in construction, landscaping, and other fields where volume measurements need to be adjusted between these two units. Other methods listed do not provide the correct conversion. For example, multiplying or adding 27 would not yield the accurate relationship between these two units, while squaring a result does not apply in the context of volume conversion. Understanding the ratio of cubic yards to cubic feet is fundamental for ensuring accurate measurements and conversions in real-world applications.
