To find the volume of a triangular prism, you would use the formula:
\[ V = \frac{1}{2} b h \cdot l \]
where:
- \( b \) is the base of the triangular cross-section,
- \( h \) is the height of the triangular cross-section,
- \( l \) is the length (or height) of the prism.
So, from your options, the correct formula is:
V = (1/2)bh * l (assuming l represents the length of the prism).
In your list, this corresponds to:
V = (1/2)bh * h if "h" is meant to represent the length of the prism. Just ensure the context is clear for each variable.
