Finding Volume of Rectangular Prisms with Layers

The video tutorial introduces the concept of volume, focusing on how prisms can be filled with identical layers to derive a formula for volume calculation. It demonstrates using unit cubes to fill a larger cube, explaining that volume is the number of unit cubes needed to fill a 3D figure. The tutorial encourages students to take notes and prepare for class discussions on calculating volume in rectangular prisms.
