Problem-solving worksheet on whales using metric units, featuring data and math questions about whale sizes and weights.

1) Fin Whale length: 20.6 m, Sei Whale length: 14.8 m
2) Gray Whale mass: 19,500 kg
3) Order of Mass: Blue Whale (1), Right Whale (2), Fin Whale (3), Bowhead Whale (4), Sperm Whale (5), Humpback Whale (6), Gray Whale (7), Sei Whale (8)
4) Order of Length: Blue Whale (1), Right Whale (2), Bowhead Whale (3), Fin Whale (4), Humpback Whale (5), Gray Whale (6), Sperm Whale (7), Sei Whale (8)
5) The Bowhead Whale is 32,000 kg heavier than the Sei Whale.
6) The Sperm Whale is 12.25 m shorter than the Blue Whale.
7) Yes, Tyger is right. The Blue Whale's mass (110,000 kg) is more than the combined mass of the 4 lightest whales (Sei Whale 22,500 kg + Gray Whale 19,500 kg + Humpback Whale 29,000 kg + Sperm Whale 31,250 kg = 102,250 kg).
8) The Blue Whale is roughly 5 times heavier than the Sei Whale.
