So now let’s look at the main objective of this video. And that’s how to find the surface area of a pyramid. Here we have a typical square-base pyramid. To find the surface area, we’ll need to work out the area of the square on the base and then the area of the triangle at the back. And the two triangles at the sides and then the area of the triangle at the front and then add them together. In fact, this diagram is getting a little bit messy and hard to work with. So sometimes, drawing the net can make things simpler.
