    to find surface area, just find area of each face and add them up.

    Q10: Triangle = 5 x 12 ÷ 2 = 30 Rectangle 1 = 4 x 12 = 48 Rectangle 2 = 5 x 4 = 20 Rectangle 13 x 4 = 52 (note you need Pythagorean theorem to find 13) SA = 30 x 2 + 48 + 20 + 52 (note 30x2 because of 2 congruent triangles) = 180
