Answer:
2
Step-by-step explanation:
volume of cuboid = 2×6×9 = 108 cm^2
108 = 2×2×3×3×3
There are three 3 but only two 2 , so we need one more 2 to make it a perfect cube.
So answer is 2
(108 × 2 = 216 which is a perfect cube as it is cube of 6, so a perfect cube of volume 216 cm^2 and side length 6cm can be made)
