## Homework Statement

An ore sample weights 17.50 N in air. When th sample is suspended by a light cord and totally immersed in water, the tension in the cord is 11.20 N. What is the total volume of the object?

## Homework Equations

B = rho * volume displaced* g

B= weight in air - weight apparent

## The Attempt at a Solution

I took the tension in the string as equal to the apparent weight. So using that I computed for the buoyancy: 17.50N - 11.20N = 6.3N

So, 6.3N = rho*volume of water displaced *g

how do i compute for the volume if the density of ore is not given?
