Exploring Geometry Formulas and Their Applications

Mr. Buffington explains common geometric formulas for various shapes, including squares, rectangles, triangles, parallelograms, circles, cubes, and rectangular prisms. He covers how to calculate area, perimeter, volume, and surface area, providing examples and step-by-step instructions for each shape. The video aims to help students understand and apply these formulas effectively.
