If the total surface area of a closed cube is 1014 cm² then the length of each edge of this cube is:

Correct option is B

Given:

The total surface area of a closed cube is = 1014 cm²

Formula used:

Surface area = $$6a^2$$ (Where $$a$$ is the edge)​

Solution: ​

Surface area = $$6a^2$$​ 

1014 = $$6a^2$$ 

$$a^2=\frac{1014}6$$= 169

$$a= \sqrt169=13$$ 

Thus the correct answer is (B)
