## Homework Statement

Objects A and B are submerged at depth of 1m in a liquid with specific gravity of 0.877. Given that density of object B is one third that of object A and that the gauge pressure of object A is 3atm, what is the gauge pressure of object B? (assume atmos pres is 1 atm and that g = 9.8m/s^2

## Homework Equations

p_gauge = P - P_atm

## The Attempt at a Solution

I think I do understand gauge pressure, that it is a difference in pressures. Specifically the diff between atmospheric pressure and the pressure in the container. But I think of gauge pressure always in terms of a tire. Thats what's confusing me. Is the question saying that the objects have enclosed air that is at a certain pressure? I have the answer but failing to put the concepts together, please help thanks
