Answer:
216 cm²
Explanation:
The surface area of a cube is the sum of the area of the six faces. So, the total surface area is
Surface area = 6l²
because l is the length of a side and l² is the area of one face.
Replacing l = 6 cm, we get:
Surface area = 6(6 cm)²
Surface area = 6(36 cm²)
Surface area =216 cm²
Therefore, the answer is 216 cm²
