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 calculate the total volume of the dollhouse, we need to find the volume of each component and then add them together.

Volume of rectangular prism:
Volume = length x width x height
Volume = 10 in x 10 in x 12 in
Volume = 1200 in^3

Volume of one triangular prism:
Volume = 1/2 x base x height x length
Volume = 1/2 x 8 in x 6 in x 10 in
Volume = 240 in^3

Total volume:
Total volume = 2 x (Volume of one triangular prism) + Volume of rectangular prism
Total volume = 2 x 240 in^3 + 1200 in^3
Total volume = 480 in^3 + 1200 in^3
Total volume = 1680 in^3

Therefore, the total volume of the dollhouse is 1680 in^3.
WRONG
I apologize for the error in my previous response. Let's calculate the total volume of the dollhouse again.

Volume of rectangular prism:
Volume = length x width x height
Volume = 10 in x 10 in x 12 in
Volume = 1200 in^3

Volume of one triangular prism:
Volume = 1/2 x base x height x length
Volume = 1/2 x 8 in x 6 in x 10 in
Volume = 240 in^3

Total volume of both triangular prisms:
Total volume of the two triangular prisms = 2 x Volume of one triangular prism
Total volume of the two triangular prisms = 2 x 240 in^3
Total volume of the two triangular prisms = 480 in^3

Total volume of the dollhouse:
Total volume = Volume of rectangular prism + Total volume of the two triangular prisms
Total volume = 1200 in^3 + 480 in^3
Total volume = 1680 in^3

Therefore, the total volume of the dollhouse is 1680 in^3.
