1.  Once we fold the sides up....the dimensions of the  base will be


(8 - 2x) (10 - 2x)


And the height will be x


So....the volume, V, is   area of the base * height  =


a)  V = (8 - 2x) (10 - 2x) x


b)  Here's a graph   of the function :




The value of x that gives the max volume is when we look at the top of the curve between x  = 0  and x = 4....this value is :   x  ≈ 1.5  in
