Big Ideas:
We can solve real-world volume problems by decomposing 3D objects into unit cubes.
To determine how many smaller objects fit into a larger object, divide the volume of the larger object by the volume of the smaller 3D object.
This lesson builds on student understanding of calculating the volume of rectangular prisms to solve real-world problems. Students are presented the task of determining how many storage boxes can fit inside of a moving truck. Students explore how to decompose 3D objects into unit cubes. To determine how many smaller objects fit into a larger object, students will divide the volume of the larger object by the volume of the smaller 3D object.
