the defnition of find the surface area of triangular prism and cylinder
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.
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
