Question
Four cubes, each having a side of 6 cm, are placed next
to each other in a straight line. What will be the total surface area of the resulting cuboid?Solution
ATQ,
When four cubes each of side 6 cm are joined side by side, they form a cuboid. Length of cuboid = 6 × 4 = 24 cm Breadth = 6 cm Height = 6 cm Surface area of the cuboid = 2 × (lb + bh + lh) = 2 × (24 × 6 + 6 × 6 + 24 × 6) = 2 × (144 + 36 + 144) = 2 × 324 = 648 cm²
