I have solved this problem but am not sure where I'm going wrong here...(adsbygoogle = window.adsbygoogle || []).push({});

Suppose you pour water into a container until it reaches a depth of 20cm . Next, you carefully pour in a 9.7cm thickness of olive oil so that it floats on top of the water.

What's the pressure at the bottom of the container? Express anser using two significant figures.

P-P_atm= ? Pa

P_1= P_atm + (rho)(g)(h)

= 1.013 x 10^5 Pa + (920kg/m^3)(9.81m/s^2)(0.097m)

= 102175.44 Pa

P=P_1 + (P_water)(g)(h)

= 1.013 x 10^5 Pa + (1000kg/m^3)(9.81m/s^2)(0.20cm)

= 104137 Pa

I keep getting this answer wrong.. I do not know what I am doing wrong. Please help!

I've tried already 1.04x10^5

1.0x10^5

and the above exact number.
