Solid geometry

Solid geometry studies three-dimensional figures, focusing on their properties, measurements, and relationships. It extends plane geometry into space, considering objects like prisms, pyramids, spheres, and polyhedra.

Important properties

• Solids have volume (the amount of space inside) and surface area (the total area of all faces).

• Key elements include faces (flat surfaces), edges (where two faces meet), and vertices (corners where edges meet).

• Common solids include prisms, pyramids, cylinders, cones, and spheres.

• Cross-sections are the shapes made when a solid is cut by a plane.
