The volume  of the granite piece  in Cm³  is 12.2 cm³
  <u><em>calculation</em></u>
 volume of granite = (volume of cylinder after placing granite - volume  of  cylinder  before  placing  granite
  = 37.2 ml - 25.0 ml = 12.2 ml
convert ml  to Cm³
that is 1 ml = 1 cm³
        12.2 ml =  ? cm³
<em>by cross  multiplication</em>
=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
