To solve this problem, we need to calculate the shaded and unshaded areas of the square and find their ratio.

### Step 1: Determine the total area of the square.
- The square has a side length of 8 cm (as shown in the diagram).
- The total area of the square is given by:
\[
\text{Total area} = 8 \times 8 = 64 \, \text{cm}^2
\]

### Step 2: Calculate the area of the shaded regions.
The shaded regions are made up of two parts:
1. A **smaller square** at the top-left corner with side lengths of 4 cm.
2. A **rectangular strip** on the right-hand side, which is 4 cm by 8 cm.

- **Area of the small square**:
\[
\text{Area of small square} = 4 \times 4 = 16 \, \text{cm}^2
\]
- **Area of the rectangular strip**:
\[
\text{Area of rectangular strip} = 4 \times 8 = 32 \, \text{cm}^2
\]

- **Total shaded area**:
\[
\text{Total shaded area} = 16 + 32 = 48 \, \text{cm}^2
\]

### Step 3: Calculate the unshaded area.
- The unshaded area is the remaining part of the square:
\[
\text{Unshaded area} = \text{Total area} - \text{Shaded area} = 64 - 48 = 16 \, \text{cm}^2
\]

### Step 4: Find the ratio of the shaded area to the unshaded area.
- The ratio of the shaded area to the unshaded area is:
\[
\text{Ratio} = \frac{48}{16} = 3
\]

Thus, the ratio of the shaded area to the unshaded area is **3:1**.
