How to 3D plot a cube and a pyramid in appdesigner

Hello,

I want to 3D plot a cube and a pyramid on a certain way in my app but I not able to do that. Until now, Ive plotted a sphere and a cylinder with surf but the following 2 are impossible for me

cube: I want to plot a cube using width, height and depth (sure is a silly thing but I didnt found anything in the forum)

pyramid: 3d plot it using the 4 vertex points.

I dont know if it is possible using surf.

Thanks in advance!

%use a regular figure only for online demonstration
if isunix()
    app.fig = figure();
else
    app.fig = uifigure();
end

app.UIAxes1 = axes(app.fig);

xvox = 2; yvox = 2; zvox = 2;   %data units in each dimension

rF = [1 2 3 4 1; 8 7 6 5 8; 1 4 6 7 1; 2 8 5 3 2; 1 7 8 2 1; 3 5 6 4 3];  %in closed form
rV = [0 0 0; 1 0 0; 1 0 1; 0 0 1; 1 1 1; 0 1 1; 0 1 0; 1 1 0] .* [xvox, yvox, zvox];

patch('Parent', app.UIAxes1, 'Faces', rF, 'Vertices', rV, 'FaceColor', 'b', 'FaceAlpha', 0.5);
view(app.UIAxes1, 3);
