Step-by-step explanation:
Surface area of a square pyramid is the area of the square base plus the area of the four triangles made from the base and the slant height.
SA = s² + 4(sh/2)
which reduces to:
SA = s² + 2sh
You are told that s = 11 and SA = 319. You can now solve for h:
319 = 11² + 2(11)h
319 = 121 + 22h
198 = 22h
h = 9 ft (answer C)

- % increase in price of gas = [(New Price - Original Price) / Original Price] x 100
% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100
% increase in price of gas = [$0.3 / $2.18] x 100
% increase in price of gas = 13.76%
