an object in completely submerged in a liquid of density .65 grams per cubic centimeter at a depth of 4 meters what is the total pressure on the object. State your answer in atmospheres.
I only get 3 tries and both my other attempts failed. Ill lose credit now please help!

Damon
4 meters is around 12 feet and 33 feet of water is about an atm but his is lighter than water, so total pressure will be about 1 1/4 atm including 1 atm at the surface
.65 grams/cc = 650 kg/m^3
pressure = 4 * 650 *9.81 Newtons /m^3 or Pascals
= 25,506 Pascals
but that is gage, not total pressure, add one atmosphere which is 101,325 Pascals
so
126831 Pascals
now convert to atm
126831 Pa/ 101325 Pa/atm = 1.25 atm

thanks so much!!!
