Question

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

Answer 1

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
