First, we need to find the area of the base of the triangular prism. The base is a triangle, so we use the formula for the area of a triangle, which is 1/2 x base x height.
Base = 2cm
Height = 3cm
Area of base = 1/2 x 2 x 3 = 3 cm²
Now, we multiply the area of the base by the height of the prism to find the volume.
Volume = Area of base x Height of prism
Volume = 3 cm² x 7 cm
Volume = 21 cm³
Therefore, the volume of the triangular prism is 21 cm³.
When finding the volume of a triangular prism, we multiply the area of the base x the height of the prism.
