Construct a new physical quantity having dimensions of length in terms of universal constant : G (gravitational constant), h (Planck's constant) and c (velocity of light). What is the order of its value?

Explanation

To construct a new physical quantity with dimensions of length in terms of the universal constants \( G \) (gravitational constant), \( h \) (Planck's constant), and \( c \) (speed of light), we can follow these steps:

### Step-by-Step Solution:

1. **Express Length in Terms of Constants**:
We start by assuming that the length \( L \) can be expressed as:
\[
L = K \cdot G^X \cdot h^Y \cdot c^Z
