This example demonstrates the calculation of the volume of prisms and cylinders. Key concepts include the product of the base area and height. Using GeoGebra commands such as Intersect, Point, Prism, Line, Cylinder, Circle, etc., the geometric shapes of prisms and cylinders can be constructed. Suitable for middle and high school students learning geometry and solid geometry.
