The total volume of the dollhouse can be calculated by adding the volumes of each individual shape.
Volume of rectangular prism: 10 x 8 x 6 = 480 in.3
Volume of triangular prism (2): 10 x 8 x 3/2 = 120 in.3 each, so total 240 in.3
Total volume = 480 + 240 = 720 in.3
Total dollhouse volume = 720 in.3 x 4 = 2,880 in.3
