In science class, Farah uses a graduated cylinder with water in it to measure the volume of some marbles. She
drops in marbles so that they're all under water and
measures the height of the water.
After dropping in 4 marbles, the height is 10 ml
After dropping in 6 marbles, the height is 11 ml.
Here are your answers from the previous screen:

are dropped in?
