Final answer:
Both the triangular prism and the right cylinder have congruent cross-sectional areas and the same height, which means that their volumes are equal according to the formula V = Ah.
Step-by-step explanation:
The question asks about the volumes of a triangular prism and a right cylinder, given that they have congruent cross-sectional areas and the same height of 5 units. According to the formula for volume V = Ah, where A is the area of the base and h is the height, since both the prism and the cylinder have equal cross-sectional areas and equal heights, their volumes are also equal. Therefore, the conclusion that can be made from the given information is that the volume of the prism is equal to the volume of the cylinder.
