Surface area of a triangular prism
Test your understanding of surface area of a triangular prism by practicing it! Work through the below exercises to use it in practice.
🎙️
What is the surface area of this triangular prism?
🎙️
First we flatten the three dimensional shape into a net and see we have two triangles and three rectangles
🎙️
For each shape, we can calculate the area
🎙️
Add them together, we have a total surface area of 84
