Weight of copper hanging/submerged

[Mattc]

A scale reads 220N when a piece of copper is hanging from it. What does the scale read when it is lowered so the copper is submerged in fresh water.

From a given chart

Density:
copper is 8930 kg/m^3
fresh water is 1000kg/m^3

I found my volume of copper to be .0025m^3

I'm just not sure which direction to go now?

What forces are involved in buoyancy? Draw a free body diagram. Also write down the definition of buoyancy? Does anything click?

Since when was volume measured in Kg?

 

[Mattc]

The forces involved are those from bottom and those on top of object. I have drawn the diagram and I think I know the connection I'm trying to make. The volume of the displaced fluid times density has to relate to the buoyant force? I think its the Newtons that's throwing me off

indeed my teach would've smacked me

geezzzz nevermind I got it. I thought i was looking over something simple.While obtaining the forces I was neglecting my 9.8m/s^2
