Assuming the open box is a cuboid with length 9 cm, width 7 cm and height 6 cm (open at the top), the outer surface area = base + 2(length×height) + 2(width×height).
Calculate:
base = 9×7 = 63 cm²
two length–height faces = 2×(9×6) = 108 cm²
two width–height faces = 2×(7×6) = 84 cm²
Total outer surface area = 63 + 108 + 84 = 255 cm².
