A box with an open top is to be made by cutting 5-inch squares from the corners of a rectangular piece of cardboard whose length is twice its width and then folding up the remaining flaps. Let x represent the width of the original piece of cardboard; express the volume (V) of the box as a function of x, and simplify the function.

  • Math -

    Width = x inches (given)
    Length = 2x inches(given)
    Height = 5 inches (given)

    Volume = 5*x*2x = 10x² in.3
