Answer: The volume of the right prism is 1560 in³.
Step-by-step explanation: The base area can be calculated by adding the area of the two triangles and the rectangle in between them. For the triangles, using the Pythagorean theorem, we find that their height is 12 inches. So, each triangle has an area of 0.51213 = 78 in². The rectangle has an area of 524 = 120 in². Adding these areas together gives a total base area of (78+78+120) = 276 in². Multiplying this by the prism’s height (5 inches) gives a volume of 2765 = 1560 in³.
