Faces, Vertices and Edges in a Triangular Pyramid

Faces, Vertices and Edges in a Triangular Pyramid

A triangular pyramid is a three-dimensional figure, in which all its faces are triangles. These pyramids are characterized by having a triangular base and three lateral triangular faces. Triangular pyramids have 4 faces, 6 edges, and 4 vertices. Three faces...
Surface Area of a Triangular Pyramid – Formulas and Examples

Surface Area of a Triangular Pyramid – Formulas and Examples

The surface area of a triangular pyramid is equal to the sum of the areas of all the faces of the pyramid. In this type of pyramids, all the faces are triangular, so we have to use the formula for the area of a triangle to get a formula for the surface area. Here, we...

Volume of a Triangular Pyramid – Formulas and Examples

The volume of a hexagonal prism is the total space occupied by the prism in three-dimensional space. We can calculate the volume of these prisms by multiplying the area of the base by the height of the prism. The area of the base is equal to the area of a hexagon. The...

Diameter of a Sphere – Formulas and Examples

The diameter of a sphere is equal to the line segment connecting two ends of the sphere and passing through the center. Diameter is an important measure of the sphere since, similar to the radius, we can also use the diameter to calculate the volume and surface area...

Elements of a Sphere with Diagrams

Spheres are round three-dimensional figures. The surface of a sphere is generated when the circumference rotates completely around its diameter. Some of the most important elements of the spheres are the radius, the diameter, the center, the poles, and the chords....
