## Homework Statement

What volume of water has the same mass as 8.58 m3 of ethyl alcohol?

If this volume of water is in a cubic tank, what is the pressure at the bottom?

## Homework Equations

denisty= m/v

Pb=Pa+density*g*h

## The Attempt at a Solution

I found the first part by setting denisty=m/v solving for m=Vrho. Then plugged that in for water in the same equation and got 6.7782 m^3. For the second part though, I thought I could use Pb=Pa+density*g*h. and the height i found by taking the 6.7782^(1/3). But would the Pa be zero since its at the bottom if not what do I use for the Pa?
