Imagine that you have three identical cubes, each with a
side length of 8 cm. These cubes are aligned and combined along their sides to form a single, elongated cuboid. Calculate the total surface area of this newly formed cuboid.Solution
When three cubes each of side 8 cm are joined to form a cuboid. Then, length of cuboid = 8 × 3 = 24 cm Breadth of cuboid = 8 cm And, height of cuboid = 8 cm Surface area of the cuboid = 2 × (lb + bh + lh) = 2× (24 × 8 + 8 × 8 + 24 × 8) = 896 cm ²
