Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister?

### Response:
Anne is 2 times as tall as her sister hence 2*(her sister's height) = 80 cm
Her sister's height = 80 cm / 2 = <<80/2=40>>40 cm
Bella is 3 times as tall as Anne hence Bella's height is 3*80 cm = <<3*80=240>>240 cm
The height difference between Bella and Anne's sister = 240-40 = <<240-40=200>>200 cm
