Terry and Bob each have an aquarium. Terry’s aquarium is 14 cm long, 12 cm high, and 10 cm wide. Bob’s aquarium is 13 cm long, 15 cm high and 8 cm wide. Whose aquarium holds the larger volume of water? Explain how you know.

Answer 1

To compare the volumes of the two aquariums, we need to calculate the volume of both.

Terry’s aquarium: volume = length x height x width = 14 cm x 12 cm x 10 cm = 1,680 cm³

Bob’s aquarium: volume = length x height x width = 13 cm x 15 cm x 8 cm = 1,560 cm³

Therefore, Terry’s aquarium holds a larger volume of water than Bob’s aquarium. We know this because it has a greater volume, which means it can hold more water.
