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 mL. What is the volume of the granite piece in cubic cm

The volume of the granite piece in Cm³ is 12.2 cm³

calculation

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

by cross multiplication

= (12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
