Question

multiple choice 1 point
what is the purpose of a spline?
○ to weaken the corner, so the box can be more easily broken
○ to add an additional surface for glue to strengthen the corner
○ to create a purely aesthetic touch making the box more visually appealing
○ it doesnt have a purpose.

Explanation:

A spline in box construction is a structural feature. Its main function is to provide extra surface area where glue can adhere, which reinforces the corner of the box, making it sturdier. Other options (weakening corners, purely aesthetic, no purpose) do not align with its practical structural role.

Answer:

To add an additional surface for glue to strengthen the corner
