When finding the volume of a triangular prism, we multiply the area of the base x the height of the prism.

Find the volume of the triangular prism.
height of 3cm
width of 2cm
length of 7cm
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.
