First we need to find the area of the triangle and the formula for that is A=1/2bh
Next we plug in what we have and we get the formula A=1/2(4x7)
When we do that math we get 14
Now we need to find the volume of the whole prism and the formula for this is V=Bh (big b means area of base)
When we plug in what we know we get V=14x13
Which gives us our final answer of V=182
