Answer:

The perimeter of a face of the new cube is:

108 cm

Step-by-step explanation:

Original edge length of cube=9 cm

Increased edge length of the cube=9×3 cm

=27 cm

The perimeter of a face of a cube=4s

where s is the edge length of the cube

Perimeter of a face of new cube=4×27 cm

= 108 cm

Hence, the perimeter of a face of the new cube is:
