I have a script that uses noise perlin to make a map. However, the map is really small and useless so I wanna know how to make it bigger.

Heres how small the map is compared to me:

Here is the script:

local Seed = 42 -- The answer to life, the universe and everything.

for X = 0,50 do -- X Loop

    for Z = 0,50 do -- Z Loop

        -- Make the part
        local p = Instance.new("Part",workspace) 
        p.Anchored = true
        p.Size = Vector3.new(1,1,1)

        --Just for style
        p.TopSurface = "Smooth"
        p.Material = Enum.Material.Grass
        p.BrickColor = BrickColor.Green()

        --The noise
        local Y = math.noise(X/20,Z/20,Seed) * 5

        --Set the position
        p.CFrame = CFrame.new(X,Y,Z)
    end
    --Wait a bit so your toaster doesn't freeze.
    wait()
end
--Tfw you write all of this and it works in one try.

Please help me make them bigger!
