Surface Area of Triangular Pyramid Calculator


Triangular pyramids are the ones which possess a triangular base and it is also known as Tetrahedron. Below is the illustration of the triangular pyramid.
Triangular Pyramid

We can calculate it's surface area using the below mentioned formula:

Surface Area of Triangular Pyramid

Example: A triangular pyramid has a base area of 40 mm, it's side length is 15 mm and perimeter is 8. Calculate it's surface area.

Solution:

Given: 

Base Area = 40 mm

Side Length = 15 mm

Perimeter = 8

We know the formula, Surface Area of Triangular Pyramid = Base Area + 1/2 x Perimeter x Side Length

 = 40 + 1/2 x 8 x 15

 = 40 + 60

 = 100 mm2

Therefore, surface area for the given triangular pyramid = 100 mm2
