Answer: The correct answer is D
Step-by-step explanation: The volume of a triangular prism can be calculated using the formula: Base area is the area of the base (which is a triangle).
Length is the length of the triangular prism (also known as the height of the prism).
Given that the base area is 12 cm² and the height (length) is 5 cm, we can compute the volume as follows: Therefore, the correct answer is D.
