Fill screen with 2D cubes dynamically accordingly Screen.width - unity3d

Question

I was trying to use a for loop to instantiate cube as much fit on the screen. So i checked how wide the screen is and is checked how wide my cube was. Divided it by each other and it didnt work.
So what i think i did wrong is that Screen.width is in pixels and renderer.bounds.size.x is in world size.
How do i fix this? I didnt figure it out on the internet..
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class move : MonoBehaviour
{
public GameObject cubePrefab;
public static bool spawn;
float times;
int screenWidth;
float objectSize;
// Use this for initialization
void Start()
{
spawn = true;
screenWidth = Screen.width;
objectSize = GameObject.Find("vork").GetComponent<Renderer>().bounds.size.x;
times = screenWidth / objectSize;
}
// Update is called once per frame
void Update()
{
if(spawn == true)
{
for(int i=0; i < times;i++) {
Vector3 pos = new Vector3(i * 2, i *2, 0);
Instantiate(cubePrefab, pos, transform.rotation);
}
spawn = false;
}
}
}

You need to calculate pixel width. In order to calculate screen position from world position use Camera.WorldToScreenPoint. This is how a function could look like:
public static float GetPixelWidth(GameObject gO)
{
Bounds bounds = gO.GetComponent<Renderer>().bounds;
Vector3 boundsPos1 = Camera.main.WorldToScreenPoint(new Vector3(gO.transform.position.x + bounds.extents.x, gO.transform.position.y, gO.transform.position.y));
Vector3 boundsPos2 = Camera.main.WorldToScreenPoint(new Vector3(gO.transform.position.x - bounds.extents.x, gO.transform.position.y, gO.transform.position.y));
return Vector3.Distance(boundsPos1, boundsPos2);
}
And this is how to use the function in your code:
// Use this for initialization
void Start()
{
spawn = true;
screenWidth = Camera.main.pixelWidth;
objectSize = GetPixelWidth(GameObject.Find("vork"));
times = screenWidth / objectSize;
}
I have tested and it works with orthographic camera
