There are three feet in a yard, therefore, the number of cubic feet in a yard is actually the number of cubic feet in a cubic yard. The answer is (3 feet x 3 feet x 3 feet) which is equal to 27 cubic feet.
It is important to remember that when you are multiplying a figure and converting it from one unit to another; both units must be in the correct format. This means that there are 27 cubic feet in a cubic yard, 1 million cubic centimeters in a cubic meter and so on. In doing so, there is less confusion about what type of measurement being talked about, be it volume or area.
According to the Annenberg Learner Interactive, the metric system is the internationally agreed upon decimal system of measurement. The metric system allows people to understand the measurement regardless of what language they speak. A cubic foot in Britain is the same as a cubic foot in China. As of 2014, Burma, Liberia and the United States are the only countries still using the imperial measurement system. The Metric System is used within industrial standards in the United States.
