Answer 2

The remaining area is 600 cm square.

Step-by-step explanation:

The side length of cube is 10cm.

Area of a cube is

$A_1=6a^2$

where, a is side length.

$A_1=6(10)^2$

$A_1=600$

The area of cube is 600 cm square.

The dimensions of cuboid are 3 cm × 2cm × 1cm.

If a small cuboid is removed from a corner of cube, then the remaining area is same as the area of cube.

Therefore, the remaining area is 600 cm square.
