You are making poster board boundary markers in the shape of square pyramids for a relay race. If you are including a ten -inch square as the bottom and you want the slant height to be twelve inches, how much poster board do you need?

    In other words, we're finding the surface area of a square pyramid, right?

    Well anyways. With the info we have, we can put it into the formula \[\huge (a^{2})+(4*\frac{1}{2}*sh*a)\] with a being the side of the square and sh being the slant height
