Solve for Surface Area of Triangular Prism Worksheet

A triangular prism is a type of prism that has 6 vertices, 9 edges, and 5 faces. The total surface area of a triangular prism is the sum of all the areas of the faces of the prism. A triangular prism consists of two triangular faces and three rectangular faces. Lateral faces are rectangular ones and bases are triangular faces.

Teaching Surface Area of a Triangular Prism Easily 

 

  • Firstly, find the area of the base and top triangles using the area of triangle formula. 


 

  • Then, find the lateral surface area. Multiply the length of the prism by the perimeter. 


 

  • Lastly, add all the areas together to get an appropriate result. 


 

Here is an example to solve a question on the surface area of a triangular prism. Let’s look at the given example mentioned below to understand more about the concept of the surface area of a triangular prism. 
 

              

                 (Perimeter of the base × Length of the prism ) + (2 × Base Area)


 

 

 

 

Q. Find the total surface area of a triangular prism which has a base area of 50 units, a base perimeter of 30 units, and the length of the prism is 7 units. 
 

Step 1: Write down all the units given. 

So, 

Base area = 50 units. 

Base perimeter = 30 units. 

Length of Prism = 7 units. 


 

Step 2: Convert the units into the same measurement, if required. 


 

Step 3: Use the Surface area formula for a triangular prism. 


 

 (Perimeter of the base × Length of the prism ) + (2 × Base Area)


 

(30 * 7 ) + 2 *50 = 210 + 100 

210 + 100 = 310 square units.
