The correct option is B 3 cm
Detailed step-by-step solution:
Volume of a cubical prism =27 cubic cm
Formula to find the volume of a cuboid =a3, where a is the length of each side of the cube.
Considering the above formula,
a3=27
⇒a3=3×3×3
⇒3√a3=3√3×3×3
⇒a=3
So, the length of each side of the cubical prism is 3 cm.
So, option C is the correct answer.
