Lateral edges the edges through the vertex of a pyramid are known as its lateral edges.

Lateral faces all faces other than the bases of a prism are known as its lateral faces.

Edges line segments common to intersecting faces of a polyhedron are known as its edges.

Lateral edges the line of intersection of the lateral faces of a prism are called the lateral edges of the prism.

The base of a pyramid is a rectangle whose length and breadth are 16 cm and 12 cm respectively. If the length of all the lateral edges passing through the vertex of the right rectangular pyramid is 26 cm, then find the volume of the pyramid in cubic centimeter?

Edge effect refers to

Vertices points of intersection of edges of a polyhedron are known as its vertices.

A pyramid is a polyhedron whose lateral faces are

The lateral edge of a regular rectangular pyramid is a cm long.The lateral edge makes an angle alpha with the plane of the base.Find the value of alpha for which the volume of the pyramid is greatest.

A regular square pyramid is placed in a cube so that the base of the pyramid and that of the cube coincide. The vertex of the pyramid lies on the face of the cube opposite to the base, as shown. An edge of the cube is 7 inches. How many square inches (approximately) are in the posi- tive difference between the surface area of the cube and the surface area of the pyramid ?
