Volume and Formulas in Geometry

The video tutorial covers lesson three, session one, focusing on finding volume using formulas. It begins with an introduction to the topic, followed by a detailed explanation of a problem involving Becky's model of a rectangular prism. The teacher guides students through solving the problem using different methods, including counting cubes and applying formulas. Two main formulas for calculating volume are discussed: using the base area and height, and using length, width, and height. The video concludes with a comparison of these formulas and an explanation of what constitutes a formula, highlighting the flexibility and application of mathematical relationships.
