Question

Cassidy says that capacity is the same as the amount Do you agree

Answer 1

I disagree with Cassidy because:
Capacity is how much something can hold (etc. the capacity of this bowl is 5 grams)

Amount is how much of something (there are ten bottles of milk in the fridge. Ten is the amount of bottles of milk in the fridge)

Hope this helps,

Answer 2

I do not agree with Cassidy because the capacity of something is not necessarily the amount of something.  Capacity is what the thing is capable of doing, holding, etc.  The amount is how much something cost, weighs, etc.  Two different meanings completely.
