A graduated cylinder is filled 25.0 mL with water and a piece of granite is placed in the cylinder, displacing the level to 37.2
kvv77 [185]

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
