What is a cubic yard most commonly used to measure?

A cubic yard is a unit of volume that is most commonly used to measure loose project materials such as soil, gravel, mulch, or concrete. This measurement is particularly relevant in construction and landscaping where materials are typically sold in bulk. For instance, when calculating how much soil or gravel is needed to fill a specific area, the volume will be expressed in cubic yards.

In contrast, the other options refer to measurements that do not typically require volumetric calculations. Fixed hardscape elements like patios or walkways are measured in square footage for area coverage, while linear flooring is measured in linear feet or square footage based on the area it covers. Structural steel is often evaluated by weight (pounds or tons) or linear measurements depending on the design and structural requirements. Thus, for loose project materials, cubic yards provide a practical unit for gauging the quantity needed for effective project completion.
