Answer 1

Given :-

• Side of the cubes = 5 cm

To Find :-

• Total surface area and lateral surface area of the resulting cuboids.

Solution :-

Area of one side of the cube :-

⟼  side × side

⟼  5 × 5

⟼  25 cm²

Total surface area :-

⟼  Number of sides × Area of one side

⟼  14 × 25

⟼  350 m²

Lateral surface area :-

⟼  (14-2) × 25

⟼  12 × 25
