Perfomance Issue With Minecraft Clone.

Trying to make a basic minecraft clone, or a cube world. To do this i am using a perlin noise 2d function to set the height of the individual cubes, works great but i have a giant problem with the framerate, if i make the world any bigger than 100x100 my framerates drops trough the roof. It seems like the gameobjects is a massive resource hog. How can i fix or improve this. Thank you! :)

Script:

 void PerlinFunction ()
     {
         
         PerlinNoise perlin = new PerlinNoise(Random.Range(0,800));//Perlin function seed
         
         for (int x = 0 ; x <100; x++)//Size of the world(x,z)
         {
             
             for (int z = 0 ; z <100; z++)//Size of the world(z)
             {
 
                 int yvalue = (int)perlin.FractalNoise2D(x,z,1,48,16);//Gets a random pelin value,used as the y size
                 GameObject cube = Instantiate(prefabgrass, new Vector3(x, yvalue, z), Quaternion.identity) as GameObject;//Instantiates a new cube at location x,PERLINNOISE,z
                     
             }
             
         }
             
     }

Looks like this:
