Question types: The measuring cylinder

Rule: Measuring volume

Read a measuring cylinder with your eyes level with the liquid; for water read the bottom of the curved surface.

Volume of an object = volume after putting it in − volume of water before. 1 ml = 1 cm³.

Example: Before: 60 ml, with the stone: 85 ml → the stone is 85 − 60 = 25 cm³

Watch out: First find what one division is worth: between 10 and 20 ml there may be 5 divisions of 2 ml.

Sample questions

  1. Question 1 Easy

    How many millilitres of water are in the measuring cylinder? Read at the bottom of the surface.

    Show the solution
    Answer: 22 ml

    How it works: One division of the scale is 2 ml; the water is at 22 ml.

  2. Question 2 Normal

    A stone was lowered into the measuring cylinder of water. What is the volume of the stone in cm³?

    Show the solution
    Answer: 40 cm³

    How it works: Before the stone: 65 ml, with the stone: 105 ml; V = 105 ml − 65 ml = 40 ml = 40 cm³.

  3. Question 3 Hard

    A stone with a mass of 80 g was lowered into the measuring cylinder of water. What is the density of the stone in g/cm³?

    Show the solution
    Answer: 2 g/cm³

    How it works: Before the stone: 65 ml, with the stone: 105 ml; V = 105 ml − 65 ml = 40 ml = 40 cm³. ρ = m ÷ V = 80 g ÷ 40 cm³ = 2 g/cm³.
