Final answer:
The volume of the triangular prism with a base of 6m, altitude of 4m, and height of 3m is 36m³.
Step-by-step explanation:
To find the volume of a triangular prism, you can use the formula V = Ah, where A is the area of the triangle base and h is the height of the prism. The base of the triangle here is 6m, and the altitude is 4m, so the area A of the triangle base is calculated using the formula for the area of a triangle, A = 1/2 × base × height. Hence, A = 1/2 × 6m × 4m = 12m². Now, with the height of the prism being 3m, the volume can be calculated as V = 12m² × 3m = 36m³.
