To find the volume of this shape, we need to break it down into two smaller rectangular prisms and then calculate the volumes separately.

### Step 1: Identify the two sections

1. **Larger rectangular prism:** This prism has the following dimensions:
   - Length = 7 cm
   - Width = 6 cm
   - Height = 1 cm

   **Volume of larger section** = Length × Width × Height  
   \[
   = 7 \, \text{cm} \times 6 \, \text{cm} \times 1 \, \text{cm} = 42 \, \text{cm}^3
   \]

2. **Smaller cut-out rectangular prism:** This cut-out is subtracted from the larger prism and has:
   - Length = 3 cm
   - Width = 2 cm
   - Height = 1 cm

   **Volume of smaller cut-out section** = Length × Width × Height  
   \[
   = 3 \, \text{cm} \times 2 \, \text{cm} \times 1 \, \text{cm} = 6 \, \text{cm}^3
   \]

### Step 2: Subtract the smaller cut-out volume from the larger volume

\[
\text{Total Volume} = 42 \, \text{cm}^3 - 6 \, \text{cm}^3 = 36 \, \text{cm}^3
\]

### Final Answer: 
The volume of the given shape is **36 cm³**.
