Let the height of the tree be x, then
18 inches / 3 feet 9 inches = x / 21 feet 3 inches
18 inches / 45 inches = x / 255 inches
45x = 18 x 255 = 4590
x = 4590 / 45 = 102
Therefore, the tree is 102 inches = 8 feet, 6 inches tall
Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm
Area of the top = area of the base = 64.5cm
Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm
Total surface area = 64.5 + 64. 5+ 330 = 459 cm²

Answer: Total surface area = 459 cm²
