उत्तर
This statement is False.
Explanation:
The dimensions of the given cuboid are 2 × 1 × 1. It is sliced into two equal parts, which are cubes.
Then, the dimensions of the cube, so formed are 1 × 1 × 1.
... The surface area of the cube so formed = 6 (Side)2 = 6 × (1)2 = 6 sq units
Hence, the surface area of the sliced cube is 6 sq units.
