Answer:
300 cubic inches
Step-by-step explanation:
The volume of the top triangular prism is 1/2(area of base)(height)
1/2(50)(6)
1/2(300)
150 cubic inches
The volume of the bottom triangular prism is the same as the top, 150 inches., because it has the same measurements.
Add the two volumes together to get 300 cubic inches, which is the volume of the figure.
