Square Face: 12cm by 12cm. Area = 12 x 12 = 144 cm 2. Triangular Face: base: 12 cm perpendicular height: 8 cm. Area: ½ x 12 x 8 = 6 x 8 = 48 cm 2. The surface area of the pyramid is (Area of Square Face) + (Area of Triangular Face x 4) So the surface area of this pyramid is 144 + (48 x 4) = 144 + 192 = 336 cm 2.
