Answer:

Step-by-step explanation:
Jason found the volume of the marble using water displacement.
To calculate the volume, we must subtract the initial volume from the final volume.

The initial or original volume is 50 milliliters.
The final volume, after the marble is added to the water, is 78 milliliters.

Substitute the values into the formula and subtract.


The volume of the marble is 28 milliliters.
