### Composite Solid Volume Calculation

#### Problem Statement:
Find the volume of the composite solid.

#### Diagram Explanation:
The diagram shows a composite solid made up of two connected rectangular prisms. The dimensions are as follows:
- The larger prism has a width of 12 feet, a length of 20 feet, and a height of 10 feet.
- The smaller attached prism has a width of 12 feet, a length of 20 feet, and a height of 7 feet.

The dimensions are labeled clearly on the diagram:
- The 12 feet width is shown at the base.
- The 20 feet length extends outwards.
- Heights of 10 feet and 7 feet, respectively, are outlined for two different sections of the solid.

#### Steps to Find the Volume:
1. **Calculate the volume of the larger rectangular prism:**
   \[ \text{Volume}_{\text{large}} = \text{Length} \times \text{Width} \times \text{Height} \]
   \[ \text{Volume}_{\text{large}} = 20 \, \text{ft} \times 12 \, \text{ft} \times 10 \, \text{ft} \]
   \[ \text{Volume}_{\text{large}} = 2400 \, \text{ft}^3 \]

2. **Calculate the volume of the smaller rectangular prism:**
   \[ \text{Volume}_{\text{small}} = \text{Length} \times \text{Width} \times \text{Height} \]
   \[ \text{Volume}_{\text{small}} = 20 \, \text{ft} \times 12 \, \text{ft} \times 7 \, \text{ft} \]
   \[ \text{Volume}_{\text{small}} = 1680 \, \text{ft}^3 \]

3. **Add the volumes of the two prisms to find the total volume:**
   \[ \text{Volume}_{\text{total}} = \text{Volume}_{\text{large}} + \text{Volume}_{\text{small}} \]
   \[ \text{Volume}_{\text{total}} = 2400 \, \text{ft}^3 + 1680 \, \text{ft}^3 \
