Final answer:
Prism B shares the same base area and height as prism A and so also has a volume of 60 cubic units.
Step-by-step explanation:
The student asks about finding the volume of prism B given that it has the same base area and height as prism A, which has a volume of 60 cubic units. However, the question contains a typo that refers to 'length of the longest edge', which is not usually directly related to finding the volume of a prism unless more information about the shape is provided. Typically, the volume of a prism is obtained by multiplying the base area by the height (V = base area × height). Since both prisms have the same base area and height, their volumes should be equal. Therefore, prism B should also have a volume of 60 cubic units.
