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.
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.
