Play with the two sliders l & h to examine different looking square pyramids.
When looking at the Net of the Pyramid you notice that the net only has 1 __________
Therefore our surface area formula is going to involve finding the lateral area (4 triangles) and 1 base. [br][br]The surface area for a square pyramid is going to look like SA = LA + B. [br][br]Then the Lateral Area would equal [math]4\left(\frac{1}{2}bh\right)[/math]. We then rearrange this to equal [math]\frac{1}{2}\left(4b\right)h[/math]. [br][br]What is 4 multiplied by the base of the triangle?
P - Perimeter of the base
The h would be the height of the triangle which would be the same as the slant height of the pyramid.
Therefore the Surface Area formula for a square pyramid is ________
[math]SA=\frac{1}{2}Pl+B[/math]
