The surface area of a prism is the sum of the areas of each of its sides, plus the two bases. As the number of sides, and their shapes are indeterminate, there is no specific formula.
The general formula is (2 x base area) + (perimeter x length)

To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
the defnition of find the surface area of triangular prism and cylinder
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
Squared. When you find surface area, you are only finding the area of the shapes that make up the three-denominational shape.
Surface area = 2LW + 2(L+W)H
