Three cubes of each side `4c m` are joined end to end. Find the surface area of the resulting cuboid.

Explanation

To find the surface area of the resulting cuboid formed by joining three cubes of side 4 cm end to end, we can follow these steps:

### Step 1: Determine the dimensions of the cuboid
Since we have three cubes joined end to end, we can calculate the dimensions of the resulting cuboid:
- **Length (L)**: The length of one cube is 4 cm. Therefore, the length of the cuboid formed by three cubes is:
\[ L = 3 \times 4 \, \text{cm} = 12 \, \text{cm} \]
