Rotations give predicted shape when applied separately but warped shape when combined (Pic)

I create hundreds of primitive cubes positioned along the top of another cube so that they are side by side. I then apply outward rotations and upward rotations to each. The upward and outward rotations look exactly as expected applied separately but result in a warped shape when combined. The code is:

//cube[] is an array of the primitive cubes

vertical:
for (int x = 0; x++; x < cube.count)
{
cube[x].transform.RotateAround(cube[x].transform.position - new Vector3(cube[x].transform.localScale.x / 2f, cube[x].transform.localScale.y / 2f, transform.localScale.z / 2f), new Vector3(0, 0, 1), 45f);
}

horizontal:
for (int x = 0; x++; x < cube.count)
{
cube[x].transform.RotateAround(cube[x].transform.position - new Vector3(cube[x].transform.localScale.x / 2f, 0, 0), new Vector3(0, 1f, 0), drawAngle);
drawAngle -= .10f;
}


Any idea what is happening?
