Measuring Volume with Metric Units

Mrs. Hunter brought some containers into the classroom so students could practice measuring volume with the graduated cylinder. She told them to first estimate the volume of each container using cubic centimeter cubes and then find the actual volume using the graduated cylinder.
Rosa used 84 centimeter cubes to fill the first container. She estimated the volume of the container to be 84 cubic centimeters.

Then she emptied the cubes from the container and filled it with water. She carefully poured the water into her graduated cylinder.
