What is the surface area of a triangular pyramid?
The surface area is a common term referred to the region covered by the plane sides of any figure/shape. In the case of a triangular pyramid, the surface area is the region bounded by its triangular sides and the slant height.
All these sides are plain lengths that surround a region. We can calculate the surface area using the pyramid’s triangular base and its slant height (Perpendicular height). The unit of the surface area of a triangular pyramid will be the square of the unit in which the lengths have been measured.
How to find the surface area of a triangular pyramid?
You can easily find the surface area of a triangular pyramid using a specific formula. Here we have listed the formula that you can use in this regard.
Surface area of a triangular pyramid = 1/2 (a × b) + 3/2 (b × s)
In this formula:
- “a” represents the base of the triangular side.
- “b” represents the perpendicular length of the triangular side.
- “s” represents the slant height.
By putting the values in the above formula, you can easily find the measure of the surface area of a triangular pyramid. Here is a solved example to understand the procedure.
Example 1:
Find the surface area of a triangular pyramid if the lengths of sides are: a = 3m, b = 5m, and s = 9m.
Solution:
As we have all values that we need to put in the above formula, so,
As we have all values that we need to put in the above formula, so,
Surface area of a triangular pyramid = 1/2 (3 × 5) + 3/2 (5 × 9) Sq. meters
= 15/2 + 135/2 Sq. meters
By solving,
= 75 m2
