Use the image to answer the question.
An illustration shows a that is shaped like a rectangular prism with two triangular prisms placed on the top, one on each side. The width of the rectangular prism is 10 inches, and the height is 12 inches. The base length of the triangular prisms on the top of the house is 8 inches each. There is a 2-inch gap between the two triangular prisms. The perpendicular height of the triangular prisms is 6 inches. A window is drawn on the face of each triangular prism, and a door is drawn on the bottom center of the rectangular prism.

To find the total volume of the dollhouse, we need to find the volume of the rectangular prism and then add the volumes of the two triangular prisms.
Volume of rectangular prism = length x width x height
Volume of rectangular prism = 10 x 8 x 12 = 960 cubic inches
Volume of each triangular prism = 1/2 x base length x perpendicular height x width
Volume of each triangular prism = 1/2 x 8 x 6 x 8 = 192 cubic inches
Total volume of the dollhouse = 960 + 192 + 192 = 1,344 cubic inches
