We want to find the volume of the prism. Recall that the volume V of a triangular prism is the area of the base B times the height h.
V= B h
Let's use the diagram to identify the prism's height and write an expression for the area of its base. Remember that the area of a triangle is half the product of any base and its height.
Now we can substitute 12* 8* 3 for B and 5 for h into the formula and calculate the volume of the prism.
