Three equal cubes are placed adjacently in a row. Find the ratio of total surface area of the new cuboid to that of the sum of the surface areas of the three cubes.

Explanation

To solve the problem of finding the ratio of the total surface area of a new cuboid formed by three equal cubes placed adjacently in a row to the sum of the surface areas of the three cubes, we can follow these steps:

### Step-by-Step Solution

1. **Let the edge length of each cube be \( A \)**:
- Since no specific edge length is given, we assume the edge length of each cube is \( A \).

2. **Calculate the surface area of one cube**:
