The volume for a triangular pyramid would be V=1/3AH, where A is the area or the triangular base, and H would be the height.
We need to find the area first. We can input the formula of the area of the triangular base, so it would be V=1/3(1/2bh)H.
In this problem, H=8, b=6, and h=4. Plug that in to the formula.
V=1/3(1/2*6*4)8. We can put that into a calculator, and get 32 cubic feet as our answer.
