Surface Area of Triangular Prisms

3-D Shape Matching! It's really important that you understand what a 3-D shape looks like "broken down" as a net! Match the 3-D shape with it's net, or "unfolded 2-D shape!"If you are having trouble with this, click on the link below to see some interactive 3-D shapes: Fill in the blanks with the right words from the word bank! Solving for the surface area of a triangular prism is a lot like solving for the surface area of a rectangular prism! In order to find the total surface area, you must first "break up " the 3-D prism into its 2-D face shapes. A triangular prism has two triangular faces and 3 rectangular faces. To find the area of the triangles multiply the base of the triangle by its height and divide by 2! Then find the area of the rectangles by multiplying their length and width. Then, add up all of your areas for the total surface area!

What values can you use as the heightand baseof the triangle? You may need to rotate your computer or rotate the image in your mind! b = 15 in, h = 9 in b = 10 in, h = 12 in b = 9 in, h = 12 What is the total surface area of the triangular prism? 468in2 500in2 540in2 700in2 Find the surface area of the triangular prism. 64ft2 96ft2 148ft2
