A triangular prism has a height of and a volume of . What is the area, , of the base of the prism? (The volume of a triangular prism is equal to , where is the area of the base and is the height of the prism.)
Explanation
The correct answer is . It's given that a triangular prism has a volume of and the volume of a triangular prism is equal to , where is the area of the base and is the height of the prism. Therefore, . It's also given that the triangular prism has a height of . Therefore, . Substituting for in the equation yields . Dividing both sides of this equation by yields . Therefore, the area, , of the base of the prism is .
