Understanding Volume of Rectangular Prisms

The video tutorial introduces the concept of volume, focusing on 3D objects and specifically rectangular prisms. It explains the use of unit cubes to understand volume and demonstrates how to calculate the volume of rectangular prisms using the formula length × width × height. The tutorial also covers calculating volume for objects not made of unit cubes, using a fish tank as an example. The lesson is interactive, with a character named Stella participating in the learning process.
