1 cubic foot example refers to the measurement of a space or item with a volume of 1 cubic foot, which is equivalent to a box that measures 12 inches by 12 inches by 12 inches. For example, a small box that holds a few books or household items may have a volume of 1 cubic foot. This measurement is commonly used in shipping and storage to calculate shipping costs based on volume.
