Cylindrical disk in water

  1. Mar 21, 2007 #1
    A cylindrical disk has volume 8.99 × 10-3 m3 and mass 8.07 kg. The disk is floating on the surface of some water with its flat surfaces horizontal. The area of each flat surface is 0.633m2. (a) What is the specific gravity of the disk? (b) How far below the water level is its bottom surface? (c) How far above the water level is its top surface?



    I solved part a, which is .898, but i have no idea how to get b and c.
    Like what equation would i use?
