Answer:
A. The volumes are equivalent.
Step-by-step explanation:
The volume of a pyramid can be found using the formula ...
V = 1/3Bh
where B is the base area, and h is the height.
Both of these pyramids have the same height, so we can compare volumes by looking at the base area.
Prism X has a rectangular base with an area of A = LW = (6 cm)(5 cm) = 30 cm². Prism Y has a triangular base with an area of A = 1/2bh = 1/2(7.5 cm)(8 cm) = 30 cm².
The two base areas are the same, so the volumes are the same.
