Question
Six cubes, each with side 5 cm, are placed side by side in
a straight line to form a cuboid. What is the total surface area of the resulting cuboid?Solution
ATQ,
Length = 6 × 5 = 30 cm
Breadth = 5 cm
Height = 5 cm
Total surface area = 2 × (30 × 5 + 5 × 5 + 5 × 30)
= 2 × (150 + 25 + 150) = 2 × 325 = 650 cm²
