# Visibly accurate scales/axes in plot3...

Hello Everyone,
The code below represents "stored boxes" in a closet (or its one way to think about it). The scales in the plotted function are accurate, but visually it is very inaccurate. I was looking for a way to change the axes to make the box appear like a box and less like a very long rectangle. Any help is welcome!!!
Accurate in terms of actual scale, but visually NOT accurate (long retangle):
Accurate in terms of visually, but NOT in terms of actual scale (looks like an actual box):
Thank you...
function BoxesInStorage()
height = 400;
width = 48+8+8;%48 box width + beam and space on each side
depth = 40*20; %20 box deep
X = [0;width;width;0;0];
Y = [0;0;depth;depth;0];
Z = [0;0;0;0;0];
hold on;
plot3(X,Y,Z); % draw a square in the xy plane with z = 0
plot3(X,Y,Z+height); % draw a square in the xy plane with z = 1
set(gca,'View',[-28,35]); % set the azimuth and elevation of the plot
for k=1:length(X)-1
plot3([X(k);X(k)],[Y(k);Y(k)],[0;1]);
