We now draw a picture of the figure resulting from the simple case - presuming we lay the flat sheet on the x-y plane with one vertex at the origin and the 8 cm side along the x- and the 10 cm side along the y-axis. Pi' are the points in the flat sheet which we cut into and form the bottom vertices of the box and the Qi's are the resulting top vertices.

Input := 


P1 = {ae,ae,0}; P2 = {ae,10-ae,0}; 

P3 = {8-ae,10-ae,0}; P4 = {8-ae,ae,0};

Q1 = {ae-be,ae-be,Sqrt[ae^2 - be^2]}; 

Q2 = {ae-be,10-ae+be,Sqrt[ae^2 - be^2]};

Q3 = {8-ae+be,10-ae+be,Sqrt[ae^2 - be^2]};

Q4 = {8-ae+be,ae-be,Sqrt[ae^2 - be^2]};
