B. Square
C. Triangle
D. Rectangle

Answer 1

To make an open box from cardboard, squares should be removed from each corner to allow the sides to fold up and create right-angled corners.

Step-by-step explanation:

To create an open box from a rectangular piece of cardboard, the geometric shape that should be removed from each corner to create flaps is a square. This allows each side of the box to be folded upwards without any gaps or overlaps and forms a clean, right-angled corner. Removing a square from each corner is the most efficient way because it enables the sides of the box to fold up perfectly perpendicular. When you remove a square from each corner of the cardboard, you are essentially removing a right angle from each corner, which creates flaps that can be folded to form the box.
