The human eye has an approximate angular resolution of `phi = 5.8xx10^(-4)` rad and a typical photo printer prints a minimum of 300 dpi (dots per inch, `= 2.54 cm`). Aminimum distance 'z' should a printed page be held so that one doesnot see the indivdual dots is ______ .

Explanation

To solve the problem, we need to find the minimum distance \( z \) at which a printed page should be held so that the individual dots printed on the page cannot be distinguished by the human eye. We will use the angular resolution of the human eye and the printing resolution of the printer to find this distance.

### Step-by-Step Solution:

1. **Understand the Given Data:**
- Angular resolution of the human eye, \( \phi = 5.8 \times 10^{-4} \) radians.
- Printer resolution = 300 dots per inch.
- Conversion factor: \( 1 \text{ inch} = 2.54 \text{ cm} \).
