Suppose a big square has 4 congruent smaller squares (each having side length [i]x[/i]) that are each cut from the corners of the larger square. [b][color=#a64d79]The 4 rectangular pieces that remain[/color][/b] are then folded up to create a rectangular prism (box) with open top. [br][br]You can move the white point to see the different-sized boxes that can be created. [br][br]Use this applet (as needed) to help you as you complete the [b]Box with Open Top [/b]performance task given to you in class today.
