Given Side of each cube = 2 cm Six cubes are joined end to end, then length of newly formed cuboid = 2 × 6 = 12 cm Breadth of newly formed cuboid = 2 cm Height of newly formed cuboid = 2 cm |
Total surface area of cuboid = 2 (lb + bh + hl) = 2 (12 × 2 + 2 × 2 + 2 × 12) = 2 (24 + 4 + 24) = 2 × 52 = 104 cm2 |
