The image shows a 3D shape made up of two rectangular prisms. To calculate the volume of the entire figure, we need to find the volume of each prism and add them together. The prisms are labeled as $1$ and $2$ in the diagram.

1. For Prism 1:

   • Dimensions: $4 \, \text{feet} \times 2 \, \text{feet} \times 8 \, \text{feet}$
   • Volume formula for a rectangular prism: $V = \text{length} \times \text{width} \times \text{height}$
   • Volume of Prism 1: $V_1 = 4 \times 2 \times 8 = 64 \, \text{cubic feet}$

2. For Prism 2:

   • Dimensions: $6 \, \text{feet} \times 3 \, \text{feet} \times 2 \, \text{feet}$
   • Volume of Prism 2: $V_2 = 6 \times 3 \times 2 = 36 \, \text{cubic feet}$

3. Total Volume:

   • The total volume of the figure is the sum of the volumes of both prisms. $V_{\text{total}} = V_1 + V_2 = 64 + 36 = 100 \, \text{cubic feet}$

Thus, the expression representing the volume of the figure in cubic feet is: $V_{\text{total}} = 4 \times 2 \times 8 + 6 \times 3 \times 2$
