Square hay bales have specific dimensions defined by their length, width, and height. Each dimension contributes to the bale’s volume, a measure of the space it occupies. The density of a bale, which represents its weight per cubic foot, is directly related to its weight and volume. The bales are typically square in shape, with three equal dimensions contributing to their three-dimensional form. Hay quality, moisture content, and storage conditions influence the preservation of the hay and impact its nutritional value.
