Volume of a triangular prism = area times length. The area of a triangle follows the equation [tex]\frac{1}{2} base*height[/tex]. We substitute in the values of base=12cm, length=40cm into the equation to get [tex]\frac{1}{2}(12)*(40)=240cm^2[/tex]. We know that the volume = area times length. Substitute the values of Area = 240 and Length = 40 into the equation to get [tex]240*40=9600[/tex]. Therefore the volume of the triangular prism = [tex]9600cm^3[/tex].
