Use the image to answer the question.

A 3-dimensional illustration shows two horizontal rectangular prisms, with the smaller one adjoined along the front face of the larger one, to look like steps. Edges that are not visible are drawn with dashed lines. The rectangular prism in front is smaller than the one in the back. The length of both the prisms is 32 yards. The smaller rectangular prism is 6 yards high and 5 yards deep. The larger rectangular prism is 16 yards high. The total combined depth of the two prisms is 15 yards.

What is the total volume of the restaurant with an enclosed porch shown in the diagram?

To find the total volume of the two rectangular prisms, we will calculate the volume of each prism separately and then sum them up.

  1. Volume of the Smaller Rectangular Prism:

    • Length = 32 yards
    • Height = 6 yards
    • Depth = 5 yards

    The volume \( V \) is given by the formula: \[ V = \text{Length} \times \text{Height} \times \text{Depth} \] So, for the smaller prism: \[ V_{\text{small}} = 32 , \text{yd} \times 6 , \text{yd} \times 5 , \text{yd} = 960 , \text{yd}^3 \]

  2. Volume of the Larger Rectangular Prism:

    • Length = 32 yards
    • Height = 16 yards
    • The total combined depth is 15 yards, and since the smaller prism's depth is 5 yards, the larger prism's depth will be: \[ 15 , \text{yd} - 5 , \text{yd} = 10 , \text{yd} \]

    Now calculating the volume for the larger prism: \[ V_{\text{large}} = 32 , \text{yd} \times 16 , \text{yd} \times 10 , \text{yd} = 5120 , \text{yd}^3 \]

  3. Total Volume: We add the volumes of the two prisms together: \[ V_{\text{total}} = V_{\text{small}} + V_{\text{large}} = 960 , \text{yd}^3 + 5120 , \text{yd}^3 = 6080 , \text{yd}^3 \]

Therefore, the total volume of the restaurant with an enclosed porch is 6,080 yd³.

The correct response is: 6,080 yd.³
