Nets, Areas and Volumes of Solids

This topic explores 3D shapes through their nets, surface areas, and volumes. Students analyse solids like cubes, cuboids, cylinders, cones, and spheres. They learn to draw and interpret nets, calculate surface area and volume, and relate these concepts to real-life packaging and storage problems.

Learning Outcomes:

The learner should be able to:

• Form and draw nets of 3D shapes.
• identify common solids and their properties including faces, edges and vertices.
• state units of measures, convert units from one form to another.
• calculate surface areas of three-dimensional figures.
• calculate the volume of cubes and cuboids.
• Solve real-world problems involving capacity and packaging.
