Jasper built a dollhouse for his younger sister. A rectangular prism has a length of 24 inches, width of 8 inches, and height of 10 inches. A triangular prism has a triangular base of 24 inches and height of 6 inches. The height of the prism is 8 inches. Which equation shows how to determine the volume of the dollhouse? V = 24 (10) (8) + one-half (6) (24) (8) V = 24 (10) (8) + one-third (6) (24) (8) V = 24 (10) (8) + one-half (6) (24) (10) V = 24 (10) (8) + one-third (6) (24) (10)
