Surface Area of a Triangular Pyramid

Surface area of a pyramid has two types of surface areas, namely: the lateral surface area and the total surface area, where the surface area of a pyramid is the sum of the areas of the lateral surfaces, or side faces, and the base area of a pyramid.

Surface Area of a Triangular Pyramid

Lateral Surface Area of a Triangular Pyramid

Lateral Surface Area of a Triangular Pyramid is calculated using the formula:

Lateral Surface Area of a Triangular Pyramid (LSA) = ½ × Perimeter × Slant Height

Total Surface Area of a Triangular Pyramid

The total surface area of a pyramid (TSA) = Lateral surface area of the pyramid + Area of the base

So, TSA = ½ × perimeter × slant height + ½ × base × height

Total Surface Area of a Triangular Pyramid (TSA) = ½ ×  P ×  l + ½ bh

where,

  • P is Perimeter of Base
  • l is Slant Height of Pyramid
  • b is Base of Triangle at Base
  • h is Height of Pyramid

Triangular Pyramid Formula

Volume of a triangular pyramid is found using the formula V = 1/3A.H. A triangular pyramid, also known as a tetrahedron, is a type of pyramid with a triangular base and three triangular faces that meet at a single point called the apex.

What is a Pyramid?

A pyramid is classified into various kinds based on the shape of the base, such as a triangular pyramid, a square pyramid, a pentagonal pyramid, a hexagonal pyramid, etc. An apex is a meeting point of the lateral surfaces or the side faces of a pyramid. The perpendicular distance from the apex of a pyramid to the centre of its base is the height or altitude of a pyramid. The perpendicular distance between the apex and the base of a lateral surface slant height of a pyramid....

Triangular Pyramid Definition

Triangular Pyramid is a pyramid that has a triangle as its base. It is also known as a tetrahedron and has three triangular-shaped faces and one triangular base, where the triangular base can be scalar, isosceles, or an equilateral triangle. A triangular is further classified into three types i.e., a regular triangular pyramid, an irregular triangular pyramid, and a right triangular pyramid....
