How Does Liquid Volume in a Soda Bottle Affect the Sound Frequency Produced?

[ledzeppelinpa]

1. A child blows on a 20cm high soda bottle, and it creates a sound of 455Hz, how much liquid is inside the bottle?


2. not nsure about the equations



3. i attempted a solution, but all came out to something along the lines of 0.018

i don't think that's right

Equation is 1/4*V*1/f = L
