I want to create a 3D square prism image with a specified hole location but in my 3D image ,it is showing only the 3D image of a square prism. How can I do that?

I have a code that I tried out but the result it gave me was a 3D square prism shape without the hole in it. Although I have coded a hole in the square image.Can someone guide me please? It is urgent for my thesis.

clc;

clear;

close all;

A = zeros(120,144) ;

[m,n] = size(A) ;

mx = m/2 ; my = n/2 ;

S = 100 ; % side of square

x = (mx-S/2):(mx+S/2) ;

y = (my-S/2):(my+S/2) ;

[X,Y] = meshgrid(round(x),round(y)) ;

idx = sub2ind(size(A),X(:),Y(:)) ;

A(idx) = 1 ;

imshow(A);

imageSizeX = 120;

imageSizeY = 144;

[columnsInImage rowsInImage] = meshgrid(1:imageSizeX, 1:imageSizeY);

centerX = 100;

centerY = 20;

radius = 4;

circlePixels = (rowsInImage - centerY).^2 ...

+ (columnsInImage - centerX).^2 <= radius.^2;

% circlePixels is a 2D "logical" array.

% Now, display it.

image(circlePixels) ;

colormap([0 0 0; 1 1 1 ]);

C = imfuse(A,circlePixels);

imshow(C);

fin_model = repmat(C,1,1,3);
