The formula to find the surface area of a triangular prism?
In mathematics, a triangular prism is a polyhedron that is made up of two triangular bases and three rectangular sides. Surface area can be defined as the total area that the surface of a particular object occupies
Answer: The formula to find the surface area of a triangular prism is bh + l (a+b+c).
Let's understand the formula in detail.
The surface area of a triangular prism can be calculated by adding up the area of all rectangular and triangular faces.
Let's solve this question with a figure given below:
The surface area of the triangular Prism = (2 × base area of a triangle) + (height of the prism × perimeter of the base)
The surface area of the triangular Prism = [2 ×(1/2)×bh + l×(a+b+c)]
Therefore, the formula surface area of a triangular prism = bh + l (a+b+c)
'b' is the base of the base triangle.
'h' is the height of the base triangle
l = height of the prism or distance between triangular bases
a, b, c = sides of the triangle
Hence, the formula for the surface area of a triangular prism is bh + l (a+b+c).
