We have a wooden piece with a volumetric mass of 800kg/m^3 and a mass of 200c.m^2 that floats on water. Find the submerged volume of the piece. (Knowing that the volumetric mass of water is 1000kg/m^3)

Please word this question correctly. Your wording is conflicting.
Well i don't know how to explain it because english is my second language

The question is to find the volume of the submerged part of the wooden piece
"volumetric mass " = density
what does this mean: "200c.m^2"
weight or mass? they are edifferent.
do you mean 100g ?? 0.1kg??
c.m^2 does not mean anything obvious
Soooooorrrryy my bad, it's volume i meant
You have to change it into m^3
so its volume is 200. 200 what? you wrote c.m^2 for your units.
Yea yes you have to change it into cubic meter
the relevant principle is :
A floating object displaces its own mass of the fluid in which it floats.
so for a body (b) in water (w) we can say
\(m_b = m_w\) for the mass of body and the mass of displaced water
thus \(\rho_b * V_b = \rho_w* V_w\) where \(\rho\) is density and \(V\) is volume
plug in numbers
