NOTE: What would the anwser be if it was a square plate with a circular hole? The metallic, circular plate of diameter D and thickness t, has a concentric hole of diameter h in its middle, as shown. Metal density is ? = 8000 kg/m3 ; D = 5 cm. 1) When h = 0 (no hole), determine the maximum thickness t [in mm] so that the plate can stay afloat on the surface of water at 20°C. 2) The...

The density of a 10 kg cube of silver is 10.5 g/cm3. What would the density of a 5 kg cube of silver be? I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???
