25 POINTS IF YOU HELP!!!

Anita and Raquel are examining 2 figures, an octagonal prism and a hexagonal prism. The two shapes are the same height and their cross sections have the same area. Anita claims that these two shapes will also have the same volume. Raquel disagrees, stating that more information is needed in order to determine the volume. Who is correct and why? (5 points)

Anita is correct because figures with the same cross sectional area will always have the same volume.
Carl is correct because you must calculate the volume of each figure before you can compare them.
Anita is correct because of Cavalieri's Principle.
Raquel is correct because Cavalieri's Principle only applies to triangular and rectangular prisms.
