To find the total volume of the dollhouse, we need to find the volume of the rectangular prism and the volume of the two triangular prisms on top.
Volume of the rectangular prism:
Volume = length x width x height
Volume = 10 x 8 x 12
Volume = 960 cubic inches
Volume of one triangular prism:
Volume = 1/2 x base x height x length
Volume = 1/2 x 8 x 6 x 8
Volume = 192 cubic inches
Volume of two triangular prisms:
Volume = 192 x 2 = 384 cubic inches
Total volume of the dollhouse:
960 (rectangular prism) + 384 (two triangular prisms) = 1,344 cubic inches
Therefore, the total volume of the dollhouse is 1,344 cubic inches. The closest answer choice is 1,320 in.3
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.

u shure
Apologies for the mistake in my calculation before. Let me recalculate:
Volume of the rectangular prism: 10 x 10 x 12 = 1,200 cubic inches
Volume of one triangular prism: 1/2 x 8 x 6 x 8 = 192 cubic inches
Volume of two triangular prisms: 192 x 2 = 384 cubic inches
Total volume of the dollhouse: 1,200 (rectangular prism) + 384 (two triangular prisms) = 1,584 cubic inches
Therefore, the correct total volume of the dollhouse is 1,584 cubic inches. Thank you for pointing that out.
