Lateral area:2.26 cm x 15 cm = 33.9 sq.cm2.26 cm x 6 cm = 13.56 sq. cmLateral area = 2 x 33.9 + 2 x 13.56 [since there are two 2.26x15 rectangles and two 2.26x6 rectangles]=94.92 sq. cm ≈ 95 sq. cmSurface area:6 cm x 15 cm = 90 sq. cm2 x 90 sq. cm = 180 sq. cm [since there are two 15x6 rectangles]Surface area = 180+94.92 = 274.92 ≈ 275 square feet. cmANSWER IS D.
