Calculating Volume of Rectangular Prisms

The video tutorial explains how to compute the volume of a rectangular prism using unit cubes and dimensions. It introduces the concept of unit cubes and standard units of volume like cubic centimeters. The tutorial highlights common mistakes in volume calculation, such as relying solely on counting visible cubes. It then presents more efficient methods, including using the area of the base and multiplying dimensions to find the volume. The video emphasizes understanding the relationship between area and volume to simplify calculations.
