front and rear panels 140 130 as such the side spacer panels 120 125 which are connected generally perpendicular to the top panel 105 also have certain dimensional and spatial relationships the side spacer panel 120 generally has the greatest width of all of the spacer panels described herein in general in order for the remaining panels to lie flush the width w side1 of the side panel 120 is generally equal to the thickness of the front panel t front plus the thickness of the rear panel t rear plus the thickness of the side panel 125 t side2 furthermore the width w side2 of the side spacer panel 125 is generally equal to the thickness of the front panel t front plus the thickness of the rear panel t rear as a general rule in order for the panels to fit flush each spacer panel connected to the panel being currently folded generally has a width equal to the sum of the thicknesses of the panels already folded under as such it is appreciated that the front panel 140 has no spacer panel since there are no panels folded underneath similarly the remaining spacer panels have widths equal to the sum of the thicknesses of the folded panels as described in detail above it is also appreciated that the longest panel from the base onto which the structure 100 stands to the top panel 105 is the front panel 140 the next longest panel is the rear panel 130 that is shorter than the front panel 140 by the width w rear.
