make it sound the same just shorten it:

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.

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

Terry's aquarium: volume = 14 x 12 x 10 = 1,680 cm³
Bob's aquarium: volume = 13 x 15 x 8 = 1,560 cm³
Therefore, Terry's aquarium holds more water than Bob's because it has a greater volume.
