How is the denominational measurement for square containers taken?

The denominational measurement for square containers is taken along one side. This method allows for a straightforward measurement that accurately reflects the size of the container, which is essential for understanding its capacity and for horticultural practices. When measuring square containers, the length of one side provides a consistent and reliable figure that can be used to calculate the overall volume of the container, ensuring that plants have adequate space for root growth.

Measuring along one side directly correlates with the container's dimensions and helps avoid any inconsistencies that might arise from measuring at angles or other points, which might not provide an accurate representation of the container’s size. This clarity in measurement is crucial for proper planting and management in arboriculture and landscaping practices.
