Answer:
Step-by-step explanation:
Base of the triangle = 6 mm
Height of the triangle = 20 mm
Area of the triangular base = (6 mm × 20 mm) / 2 = 60 mm²
Now, we have the area of the triangular base and the height of the prism, which is 12 mm.
Volume = 60 mm² × 12 mm = 720 mm³
So, the volume of the triangular prism is 720 cubic millimeters (mm³).
