What is the capacity of a bottle of water that is 8in tall?

Answer 1

What capacity would you like? I all depends upon the cross sectional area of the bottle (along with the shape of the bottle).

For example, assuming a cylindrical bottle:

• if the bottle has a cross sectional area of 1 in² then its capacity is 8 cubic inches (about 130 ml);
• If the bottle has a cross sectional areas of 3 13/16 in² = 3.8125 in² then its capacity is 30.5 cubic inches (about 500 ml or ½ litre);
• if the bottle has a cross sectional area of 7 5/8 in² = 7.625 in² then its capacity is 61 cubic inches (about 1 litre).

Answer 2

The answer depends also on the cross sectional area of the bottle. Without that information, there can be no sensible answer.
