The sides of footings are molded by boards known as what?

The correct answer is that the sides of footings are molded by boards known as form boards. Form boards are essential in construction as they provide a temporary structural frame that holds concrete in place while it sets. These boards are typically made of wood or other materials and are shaped to create the desired dimensions and slopes of the footing.

Form boards ensure that the concrete achieves the required strength and shapes needed for the foundation. They help contain the wet concrete until it cures and provides the support needed for building structures above it. Unlike other types of boards mentioned, such as support boards, haunch boards, or edge boards, form boards are specifically designed and utilized for creating forms for concrete placements.
