A uniform block of height 0.260 m, floats in water of density 1000 kg/m3. The bottom of the block is 0.2530 m below the surface of the water. What is the density of the block? fb = mg m=(pf)(v) d = m/v What i did was find the mass, using the volume of what is submerged, then when i found d using equation 3, i used the v of the whole block. I know im mixing something up here, but im not sure what it is..
