Volume = (1/2) × base × height (of triangle) × length (of prism). So base area of triangle × length.

Which base and height?

Base = one side of the triangular base; height = perpendicular height of that triangle; length = depth of the prism.

The formula assumes the prism is right (lateral edges perpendicular to the base).
