[color=#ff0000]We are learning to:[/color][br][list][*]Comprehend that if two solids are cut into cross sections by parallel planes, and the corresponding cross sections on each plane always have equal areas, then the two solids have the same volume (Cavalieri’s Principle)[/*][/list][color=#ff0000]We are successful when we can:[/color][br][list][*]Know that if two solids have equal-area cross sections at all heights, they have the same volumes[/*][/list][br][b]Approximately symbol ≈[/b]

For each pair of solids, decide whether the volumes of the two solids are equal. Show your calculations and explain your reasoning.
