You are making poster board boundary markers in the shape of square pyramids for a relay race. If you are including a 12 inch square as the bottom and you want the slant height to be 14 inches, how much poster board do you need?
252 in2
420 in2
480 in2

Best ResponseYou've already chosen the best response.2\[A_{\text{square}}=12 [\text{in}]\times12 [\text{in}]=144 [\text{in}]^2\] \[A_{\text{triangle}}=\frac{14 [\text{in}]\times12 [\text{in}]}2=84 [\text{in}]^2\] \[SA_{\text{square pyramid}}=A_{\text{square}}\quad+\quad4\times A_{\text{triangle}}\]
