What is the surface area of the pyramid shown to the nearest whole number? the diagram is not drawn to scale. a. 144 ft^2 b. 252 ft^2 c. 108 ft^2 d. 63 ft^2

Surface Area (S.A.) is the sum of the area of the base and all of the faces

Area of the base = 6 x 6 = 36
Area of one of the faces = (1/2) b x h = (1/2) x 6 x 9 = 27

There are 4 faces so the sum of the areas = 36 + 4(27) = 144 ft²
