Plot cube with certain length, width and height.

I want to plot a beautiful 3D cube with certain length, width and height. Please help its urgent. I do not know MatLab programming.

This code gives me l, w and h.

disp('"Cybill Technologies"');                       
disp('By Asawira Emaan   Khan');          
disp('19I-2167');          
disp('                                  ')
n = input('Press 1 to continue');                 
while(n == 1);                                     
v = input('Enter volume.');                        
width = (9*v)/20;                                  
w =nthroot(width, 3);                              
l = 2*w;
h = v/(2*(w*w));                                 
cost = 20*(w*w) + (18*v)/w;                        
disp('Total cost: ');                              
disp(cost);                                        
disp('Width: ');                                   
disp(w);                                           
disp('Length: ');                                 
disp(l);                                           
disp('Height: ');                                  
disp(h);  
%I need code there to plot a 3d cube for given dimensions. 
n = input('Press 1 to continue or any other key to terminate');
end;

Hi,

As per my assumption you would like to plot a cuboid/cube with length,width and height as input.

For plotting a cube, you can add the following function in your code.

disp('"Cybill Technologies"');                       
disp('By Asawira Emaan   Khan');          
disp('19I-2167');          
disp('                                  ')
n = input('Press 1 to continue');                 
while(n == 1)                                  
v = input('Enter volume.');                        
width = (9*v)/20;                                  
w =nthroot(width, 3);                              
l = 2*w;
h = v/(2*(w*w));                                 
cost = 20*(w*w) + (18*v)/w;                        
disp('Total cost: ');                              
disp(cost);                                        
disp('Width: ');                                   
disp(w);                                           
disp('Length: ');                                 
disp(l);                                           
disp('Height: ');                                  
disp(h);  
draw_cube(l,w,h)
%I need code there to plot a 3d cube for given dimensions. 
n = input('Press 1 to continue or any other key to terminate');
end

function draw_cube(length, width, height)
    % Define the vertices of the cube
    vertices = [0 0 0; 
                length 0 0; 
                length width 0; 
                0 width 0; 
                0 0 height; 
                length 0 height; 
                length width height; 
                0 width height];
    
    % Define the faces of the cube
    faces = [1 2 6 5;
             2 3 7 6;
             3 4 8 7;
             4 1 5 8;
             1 2 3 4;
             5 6 7 8];
    
    % Draw the cube
    patch('Vertices', vertices, 'Faces', faces, 'FaceColor', 'blue', 'FaceAlpha', 0.5);
    
    % Set axis labels
    xlabel('X');
    ylabel('Y');
    zlabel('Z');
    
    % Set aspect ratio
    axis equal;
    
    % Set view
    view(3);
end

Hope this will help with your query!
