This example demonstrates the calculation of volume and surface area for a cuboid. It involves core mathematical concepts such as cuboid geometry, volume formula (length×width×height), and surface area formula (2×(length×width + length×height + width×height)). The construction uses GeoGebra commands/objects: Points, Segments, variables (panjang, Lebar, tinggi), and texts (text7, text8, teks1-6, teks7, text3, teks8). Suitable for middle school students and above learning solid geometry and formula application.
