Triangular prism surface area made easyTo find the triangular prism surface area, we add the areas of all the five faces. Lesson#1 on finding the surface area of a triangular prism Lesson#2 on finding the triangular prism surface area How to find the surface area of a triangular prism?As you saw in the triangular prism nets section of this site, all kinds of triangular prisms are made up of two triangular and three rectangular faces. Find the area of all the five faces and add them together to find the total triangular prism surface area. Hence, the key to find the surface area of a triangular prism is to find the area of five of its faces. 
Triangular prism surface area is the sum of areas of its five faces. There is no need to be panic, and if kids know how to find the area of a rectangle and the area of a triangle, then they can easily find the surface area of a triangular prism. The need is to know how to make the net of a prism. The alternative method is to imagine all the faces of the prism one by one. This way adding the area of all the faces the surface area of the shape can be obtained. 
What it takes to find the surface area of a triangular prism?If you know how to find the area of a rectangle and the area of a triangle; then you can find the surface area of a triangular prism easily. To find the area of a rectangle we need to multiply base and height or the rectangle. Some times base and height of a rectangle are called length and breadth (width) of the rectangle. Students need not to confuse with these terms, as they need to multiply both the given lengths of adjacent sides of a rectangle to find its area. To find the area of a triangle, multiply the length of base to the height of triangle from the same base and divide the answer by 2. Grades six and seven give a very good opportunity for kids to learn how to find the area of basic two dimensional shapes. This curriculum includes the lessons on finding areas of rectangles and triangles. 
Lessons to find triangular prism surface areaBelow are the key lessons to find the surface area of a triangular prism. We encourage the learner to go through the lessons before printing the worksheets for practice. Most of these lessons have step by step instructions so that students understand the concept of surface area. Reviewing lessons give a hang of the concept to students and give them confidence to do any kind of problem on the concept. Lesson#1 on finding the surface area of a triangular prism Lesson#2 on finding the triangular prism surface area The above methods were to find the surface area of the triangular prism without using its net. Below are two more lessons on finding the surface are but this time we will use the net of the triangular prism.
