A cube of wood having an edge dimension of 20.0 cm and a density of 650kg/m^3 floats on water. a) what is the distance from the horizontal top surface of the cube to the water level?(adsbygoogle = window.adsbygoogle || []).push({});

b)what mass of lead should be placed ont eh cube so that the top of the cube will be just level with the water?

A is 7.0cm

B is 2.80kg

Vfluid/Vobject= Dobject/Dfluid

I figured out how do to the first part but im having trouble trying to find out part B.

I know you have to use V=m/d but the problem is I can't seem to find volume.
