Any three-dimensional geometric shape’s surface area equals the sum of all the contained solid’s faces or surfaces. Four triangle-shaped faces make up a triangular pyramid. As a result, the area of the base, its perimeter, and any side’s slant height are all factors in the formula used to determine a triangle pyramid’s surface area. The surface area is always measured in square units like cm^2, m^2, or ft^2.
The surface area of a triangular pyramid is = Base Area + ½ (Perimeter x Slant Height)
The lateral surface area and the total surface area are the two different types of surfaces that make up a triangular pyramid. A triangular pyramid’s surface area can be calculated by multiplying its base area (again, a triangle) by the sum of its three lateral areas. Let’s examine both in depth.
The whole surface area of a triangular pyramid, excluding the base, is known as the lateral surface area. It is calculated by adding up the triangular faces’ surface areas. You can use the steps below to calculate a triangular pyramid’s lateral surface area:
Moreover, you can also use the following formula to get the lateral surface area of the triangular pyramid.
The lateral surface area of a triangular pyramid = ½ x (Perimeter of the base x Slant height)
If the base is an equilateral triangle, the perimeter will be = 3x one side of the triangle
So the lateral surface area of the triangular pyramid = 3/2 x (Side length x Slant height)
You will get a solved problem in the following picture regarding the formula for the surface area of a triangular pyramid.
Download the following PDF to practice more to become familiar with the formula for the surface area of a triangular pyramid.
A surface’s total area is referred to as an object’s total surface area. The pyramid’s base area and lateral surface area are added to determine its overall surface area.
The total surface area of a triangular pyramid = Base Area + Lateral Surface Area . Now, the area of a triangle = ½ x (Base x Height) .
So, total surface area = ½ x (Side of the Base x Height of the Base) + 3/2 x (Side length x Slant height) .
You will get a solved problem in the following picture regarding the formula for the surface area of a triangular pyramid.
