## Homework Statement

You are a secret agent deep in the jungle, escaping from the pursuing villains. You see a stream and reeds, so you cut off a reed, jump into the stream and lie about half a metre under water breathing through the reed. Assuming that the area of your chest is approx. 30x30cm, can you breathe?

## Homework Equations

"pressure = hdg" is the only thing given

h= depth

d= density

g= gravity

## The Attempt at a Solution

ive been trying to figure this out for days... there's many ways to work it if we knew other numbers but i don't know how to get it from this without assuming water density, which unless I am wrong is variable by temperature? we arent given a temp...

am i just blindly reading into this too much and its actually really simple?

1 thing though, PLEASE don't give me an answer, i just want a method, having an answer doesn't help if a similar question comes up in my exam.
