Yes..I will work without "let".

Since I tried to reinstall Openscad. As I am working in ubuntu, it is taking
the version of 2015.03 - 1 only. It is not updating.

Thanks and Regards,

Sunag R A.

The code:

linear_extrude(size) {
for ([0:499]) {
a = rands(0, 360, 1)[0];
translate(pos(radius, size) * [sin(a), cos(a)])
square(size, center = true);
}
}

is working fine. Now I can build upon this on what I needed other than cube.

Thank you so much everyone.

translate([0, 0, -0.5])
circle(14, $fn = 50);

for (x = rands(-14, 14, 50), y = rands(-14, 14, 50))
if(norm ([x,y])<14-0.707107*0.5  )  translate([x, y, 0.25]) cube([0.5, 0.5,
0.5],center=true);
