Find the surface area of the square pyramid
1 answer:
Well, is very plain vanilla.
notice, the square pyramid has a square on its base, thus is called that, the base is 4x4 in area.
it also has 4 triangular faces, each triangle has a base of 4 and an altitude or height of 6.
sum up the area of the base and the triangular faces, and that's the total area of the pyramid.
![\bf \stackrel{\textit{square's area}}{(4\cdot 4)}~~+~~\stackrel{\textit{4 triangular faces' area}}{4\left[\frac{1}{2}(4)(6) \right]}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Bsquare%27s%20area%7D%7D%7B%284%5Ccdot%204%29%7D~~%2B~~%5Cstackrel%7B%5Ctextit%7B4%20triangular%20faces%27%20area%7D%7D%7B4%5Cleft%5B%5Cfrac%7B1%7D%7B2%7D%284%29%286%29%20%20%5Cright%5D%7D)
