the pressure thing is a law- look at pascal's vases. Pressure in a liquid is not affected of the base changes. - do you see A area in the formula pgh ;)

HEY CAN ANYONE PLEASE TELLL MEE IF THEY USED EFFICIENCY EQUATION TO FIND POWER OUTPUT?????????
efficiency = power output/power input * 100???
and did they get 54W or something like that??
and d fraction is 1/8????
