This example demonstrates how to calculate the volume of a composite body using GeoGebra. Key mathematical concepts include: decomposing into multiple cuboids to calculate volume; applying and justifying the formula for the volume of a cuboid; investigating the effects of length changes on surface areas. The construction summary uses GeoGebra commands such as Shuffle, Element, Cone, Textfield, etc. Suitable for 5-6 grade students.

AI Drawing Prompt Reference

The figure consists of multiple three-dimensional cones and prisms combined to form a composite solid structure. It includes several cones connected to prisms, which may serve as bases or supports for the cones. The overall shape is used to intuitively demonstrate volume calculation methods, with various parts connected through spatial relationships to show the hierarchical nature of the geometric construction.
