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.
Length: 7 Width: 2 Height : 3
First, we need to find the area of the base of the triangular prism. Since the base is a triangle, we use the formula for the area of a triangle which is 1/2 x base x height.
Base of the triangle = 7
Height of the triangle = 2
Area of the base = 1/2 x 7 x 2 = 7
Now, we can find the volume of the triangular prism by multiplying the area of the base by the height of the prism.
Volume = Area of the base x Height
Volume = 7 x 3 = 21
Therefore, the volume of the triangular prism is 21 cubic units.
