Complete the following table Solid figure Number of faces Number of edges Number of vertices Square pyramid 5 Cone Sphere 1 Cylinder 3 Cuboid Tetrahedron Triangular prism

3 D objects have one or more surfaces either plane or curved or both. These surfaces are called faces of the solid. The faces intersect forming a line segment called the edge of the solid. These edges intersect at points called the vertices of the solid. Based on the above information we are required to complete the following table.
