volume of cuboid is = 18 * 12 *8
= 1728 cm ³
side of the cube is =( 1728)⅓
= 12 cm
surface area of the cube formed is = 6*( 12)²
=864 cm²
= 1728 cm ³

Step-by-step explanation:
Volume of cuboid= l × b × h
= 18 × 12 × 8
= 1728 cm^2
Volume of cube = a^3
Since, The volume of cuboid is equal to voluke of cube.
1728 = a^3
a = 12 cm.
Therefore, side of the cube = a = 12 cm.
Surface Area of Cube = 6 × a^2
= 6 × 12^2
= 6 × 144
= 864 cm^2.
