The thickness of the surface is 0. Or do you want to look from the side?

Plot3D[x^5 y, {x, -1, 1}, {y, -1, 1}, PlotRange -> All,
ViewPoint -> {0, -3, 0}, PlotPoints -> 40, Mesh -> False,
AxesLabel -> {x, y,  TraditionalForm[x^5 y]}, ImageSize -> 400,
BoxRatios -> {1, 1, 1}];

P.S.: I did not read your 2nd message before answering the first one.
