Understanding Rectangular Prisms

This video tutorial introduces the concept of a Balok, a three-dimensional shape formed by rectangles or squares. It covers the properties of Balok, including vertices, edges, and faces, and explains how to calculate the surface area and volume. The tutorial also discusses diagonal planes and space diagonals, providing formulas for their calculation. Example problems are solved to demonstrate the application of these concepts.
