Two identical cubes of edge 6 cm are joined to form a cuboid. Find the total surface area of the cuboid.
Length of the cuboid = 6 + 6 = 12 cm
Breadth of the cuboid = 6 cm
Height of the cuboid = 6 cm
Total surface area of the cuboid = 2 (lb + bh + hi)
= 2(12 x 6 + 6 × 6 + 6 ×12)
= 2(72 + 36 + 72) = 2(180) = 360 cm^2
