A geometrical solid is a three-dimensional shape that has specific properties such as volume, surface area, and angles. Two examples of geometrical solids are the torus and the PRISM. A torus is a doughnut-shaped object with a circular cross-section. It is formed by revolving a circle around an axis that does not intersect the circle. A PRISM is a polyhedron with two parallel faces that are the same size and shape. It is formed by connecting two or more polygons together.
